Back in the sixties and seventies we would install our exhaust system without the H pipe initially. Spray some cheap white paint on the exhaust pipes starting 6" behind the collector For an additional 18". Take the vehicle out and drive it for about an hour and put it back on the lift. A short heat discolored area will show up on the pipes. That's where you install your balance tube. Works equally as well without headers. Just spray a longer area. This may sound crude, but it worked quite well. Sometimes you will find that but heat spots are not in the same location on both pipes. Some people would take the average distance and weld the pipe in there. Others would install the balance tube exactly where the heat marks were.
I was wondering if they were going to mention this in the video.
Nice tip
Interesting trade skill! :D
Thanks for sharing :)
Let me save you 5 minutes of your life. Video summary: The H pipe may be better in your application or the X pipe may be better in your application or maybe even the Y pipe may be better in your application.
Mr Bob y pipe lol 😂 Italian retart our crusin
Mr Bob loool
I can't find this application on my Google play.
LMAO
That’s no shit! All performance cars of the 60s and 70s didn’t use this shit. And they were just fine. Bullshit for ppl to buy more useless parts
Placement is key here, old school trick is to draw a line running back along the pipes in crayon, run the engine, where the line stops burning is where you put the crossover. 👍
@slade bonge It was a trick used by Bill 'Grumpy' Jenkins back in the day, aparently he found that the line drawn in crayon stopped burning where the exhaust gasses cooled down and began to expand, he saw HP and TQ gains throughout the rev range when he put a balance pipe at this point in the system, although im sure todays off the shelf systems are designed using the same principles, but might be of help if you are building your own. But dont make the mistake of thinking bigger is better, if you go too big it allows the gasses to expand and cool down faster, this actually creates backpressure, 3in pipe is usually plenty for a street driver. Happy building!
@slade bonge I cant help but smile when i see guys in small displacement cars with 4in pipes, because its loud they think its faster, cherrys sound mega in v8's too!

We did this on motorcycles back in the day too to determine length.
H Pipe= Old-School Classic Rumble.
X Pipe= NASCAR/Exotic Car Sound.
CRUZ_GT My choice is true dual, deep uneven engine burble.
LiveBig7 only gonna work properly on a vehicle that you can run equal length pipes on.
The GMT400's have a side mount gas tank, so you can cross in the front, but still have to run the pipes down one side, then split back to have "dual" exhausts.
But your sound won't be like "true duals" since the pipes are distinctly different lengths.
CRUZ_GT love Xpipes for mustangs
So you mean that the X pipe is that tinny loud noise but the H pipe is the old Skool loud rumble I’ve got a Audi S6 V10 what do you think is best I’m looking for the loudest koz the car is to freakin fast allready so speed is not an issue
good newz look up the sound comparison on youtube, I think xpipe is better, it's louder
After watching the video and reading comments I am more confused than ever🤔
me 2!
Kevin Grazier
Easy,
Stupid is true dual.
Low end torque is H pipe.
High end torque is X pipe.
When in doubt; straight pipe
I know right
TL:DW
Get an h-pipe.
It all comes down to what RPM range and throttle opening you drive the most with. If you spend most of your driving time at or near WOT higher RPMS, go for the X-Pipe. If not, go for the H-Pipe. There's a reason the OEMs still use H-Pipes in their exhaust systems even on their higher output engines, and the majority of people will be well served by an H-Pipe over an X-Pipe.
tf is a wot rpm
@@JameGoFastwide open throttle. It's a common term. WOT
@@JameGoFastfix your name jamedontgofast
I went with an H-pipe on my '06 Merc CLS500 because I wanted the old school V8 sound. Glad I did.
Bro I just bought a cls500. How are you finding the H pipe? I was thinking of an X pipe..
@@yaseen123123 I'll be honest it took a long journey to get the exhaust how I wanted it on mine, I started with a rear muffler delete & it droned like crazy. Long story short I ended up with two glasspacks at the rear, a pair of J-pipes to eradicate the drone & I did run it for a while with an H-pipe in place of the resonator. It sounded good but there was still a small amount of drone, so I lost the H-pipe & had a pair of glasspacks put in it's place. It's now perfect for me, no drone & the V8 soundtrack is always there without becoming annoying on long trips. For me no crossover at all sounds best as it gives the true pulsing V8 sound, which Mercedes seemed to do their best to smooth out & eradicate. But it's all down to personal taste, some prefer an X-pipe which gives a more raspy, exotic car sound, some prefer an H-pipe which gives more of an old school V8 sound, I prefer no crossover at all, as for me it should have the signature V8 pulsing, woofly sound. The difference between an X-pipe, H-pipe or even no crossover at all is minimal anyway, there's only a couple of BHP in it.
X pipes are more raspy, H pipes are deeper more rumbly in V8s at least
Im just going to use all 3, then I can't go wrong
Think of how much horsepower you’ll get
@@gabehintzsche2064 like 50 at least
Great video on the very basic on how exhaust gasses pulsate , and how a properly turned exhaust system promotes vacuum scavenging . ... COOL
Ive spent around 15grand at summit and never once was I let down. Had one item that needed to be returned but that was due to manufacturer flaw. Thanks summit.
Agree Dr Tony! Summit is a great place to do business. Great customer service and excellent shipping times! Thanks Summit!
Engine masters just did a dyno shoot-out comparing straight duals, H-pipe, and X-pipes. They did multiple pulls with each, exhaust size and muffler's were the same for each test. The variance between the three was shy of 4 ft/lbs of tq and 1.5 hp. Maybe NASCAR finds those numbers important, but for the rest of the planet running full exhaust you'll never notice any power difference.
The real difference is sound, and packaging. The X-pipe sounds best, and is the hardest to fit under the car.
Rene Jelles b,
Rene Jelles they do tje pulls at gull thottle all so tje does not show part throttle
Rene Jelles is that on RUclips. Wanted to see that.
So you think there are bigger differences at part throttle? OK...
It's currently on motortrend on demand, but should drop on youtube in the next two weeks.
While I needed to listen to this explanation twice, I finally understood the nuances that helped me make the right choice. Thanks for posting.
Who else was dizzy watching that exhaust pipe flow? I need a drink.
There is one other consideration which was not mentioned. Yes, we all want more power, but is there something else we want? Yes! Sound quality....it's one of the reasons so many of us love Ferrari's. They just sound so damn good. I place "X" pipes on all my cars, not just for better performance, but for a noticeable improvement in the exhaust note, with the same mufflers. I learned about this when I was a spectator at Laguna Race Way....I noticed some V8s sounded better than others. After the practice session, I went to the pits and asked the crew why their car sounded so good, compared to the others. They told me they were using an X pipe, vs what the other guys were using: H or Y pipes.
How about crack pipes?
No Future 68 LMAO!
Omfg I'm dead 😂😂
Dude this made me lol
Crack pipe is bad mmmmmmk!
How about Crackhead?
I put an 3", stainless steel x pipe kit on my 81 Camaro with 511hp. I started it up, and it sounded really bad. Sounded European.
I immediately dropped the exhaust, cut a slit, and then slid a plate of stainless into the slit and welded it all up. The plate kept each pipe separate.
WOW WHAT A DEFERANCE! true dual exhaust sound, almost stereo... Beautiful and gurgaly.
Also, the set of headers used on the dyno weren't that great. I revved it up, and on the deceleration of the engine, it would kinda back fire here and there. Once I got it installed in my car, with equal length, long tube, 1.75" primarys, ceramic coated hooker headers, no more backfires at all. Just pure revs and decelerations. So glorious.
Summary: a smaller diameter exhaust may be better, or not, and an X pipe may be better, or not.
yup...that settles it eh? lol
Awesome video, love the depth of the information.
Love his straight talking delivery on Concepts. I am a relative new entry & just bought a '65 Convertible with a '68 302, auto and am looking to get around 350+/- HP and relative torque. Much of the Media" I see around Mustang resot/mod,... are dunk on uber garage lingo that can be a barrier to entry for me. I am also a conceptual learner, rather than step by step. Kudo Carl Pritts!
It’s a great explanation of how exhaust systems work. So many automatically think that larger diameter pipe is better. However, I have seen a number of tests showing that there is little to no scavenging effect after the cats/test pipe area-so an h pipe or x pipe would play little role in that realm
Scavenging can also be adjusted with cam timing. Changing the duration and overlap of the intake and exhaust can have a huge effect
@@chrismoriarty3342 that is true in cases where that’s possible-or is the change in scavenging more of a biproduct of the cam timing adjustment? You could argue that cam timing is adjusted for purposes other than scavenging
I have an H-pipe on my 418 stroker. With my thumping cam the H-pipes rocks.!!!
Thank You. Had this conversation today.
I have always been a 1970 Roadrunner fan, but damn that glass pack sound never gets old to hear & sexy to hear.
Very informative! Thanks for sharing...
Thank you for watching!
Thank you for a most informative video. Solid presentation. I learned a lot.
Thank you for watching!
2014 Mustang GT with a GT500 exhaust. It uses an H pipe and couldn't be happier with the sound. Personally, I think it's all preference. The X pipe has garnered more attention because it's been talked about more. I'd be willing to bet a lot of enthusiasts don't even know what an H pipe is. I prefer more muscle sound instead of rasp. But, again, it's all preference.
I have a 5.0 tvr/rover V8 Capri with 1-7/8" primaries into 4-1 collectors and dual 3inch pipes with no crosspipe,it sounds like thunder.I built a custom dual set up for our ST220 again without any crosspipe,it is slightly noisy at WOT but sounds nicely deep and rumbly from low to middle range.
this man knows his stuff
My experience removing my H pipes for X pipes is. I noticed that the H pipes sounds better and deeper, X pipes it sounds good but not very deep, the X pipes gives you arround 4 hp or little more than H pipes. I honestly miss my H pipes I regret removing it. I drive 2002 mustang Roush stage 2 with side exhaust. By the way every engine will sounds different. With new mustang will sound better than mine, 5.0 cayote sound good. mine is 4.6 2v. I will do a cayote swap when this engine goes bad. Future plan. I hope this will help guys. X and H
You 'noticed' by watching the Engine Master's dyne test, huh?
I have a 2016 5.0 with an x pipe, RTR Magnaflow axlebacks and it has a great tone especially at start up. I don't like obnoxious loud so I can still sneak out of town. Would've went with the competition mufflers but my neighbors would probably hate me since it is my daily driver. One still says car is too loud but x pipe ain't going nowhere! 🙄😁
Way back in the pre-Internet days, but after Fred Flintstone, I had a 1969 Cutlass with a HO 350, PowerGlide and a Holley 650 double pumper. _STRAIGHT_ 2" pipes out of the headers (insulated) back to a pair of cutouts. One leg of the cutouts went to the mufflers (Hush Thrush's) and the other pointed straight at the ground just behind the rear axle. With the CO's closed it dynoed from 325 - 385 between 2 and 4k RPM. Opening the CO's added about 30HP across that range.
'85 Ford F-250 with a 460, mild build, 250 hp at rear tires with 350# tq. I installed an X-pipe where the 2 exhaust pipes come together. I installed an O2 bung and have an O2 sensor to monitor air fuel ratios for tuning. I plan on EFI like a Holley later and this is a good location for the O2 sensor as it will monitor both sides mixed together.
An H pipe creates a balancing of pulsations between each cylinder bank upon scavenging, it does enhance a smoother throttle response somewhat.....doesn't necessarily enhance the expulsion of exhaust.
I liked the fact that the narrator is realistic , an exhaust upgrade does not always result in better performance.
Breath in breath out... Incoming air increases will require higher exhaust flow escaping. I noticed a significant increase in horsepower after installing a fresh new stock exhaust pipe. Performance pipes only help on the higher end revs and usually will help only around 70mph and up. . It will actually slow the car off the line a tad bit.
Thank you, Kos!
Great little video. Thanks
Glad I watched this! Thumbs up!
I was thinking about after market exhaust, after watching this I'll stick with stock, you may have saved me some 💰💵💵💵💰💰👍🏻👍🏻
I have a question. How can I get more flow and scavenging from a single pipe exhaust system? I have a V6 mustang? And I want to keep that sleeper appearance when I install a centifugal supercharger on my 3.8.
Good Day. Excellent information. Thank You & Best Regards.
I appreciate that lil lesson Carl
Thanks for watching, Clayton!
Depending on the Application, my 03 Cobra sounds badass with the X especislly deceleration. Those pops and crackles. But on the other hand our 5.0L Range Rover without the X sounds Epic.
The pops and crackles are a sign of air getting in , system isn't fitted properly.
You guys need to fire your web designer. Worst website ever. Almost impossible to find most parts I need

U is the best because you can wrap back around to the turbo and then exit out the bumper
I Got AUDI a6 c5 2.4i 121kw 2001y and i got y pipe do i can to go for true dual exhaust is it possible and should i go for it ?
@@reyzo3411 fohget abouttit
DO NOT wrap your headers all the way to the flange. They will keep the first bend too hot if you do a quality wrap! After a few years on the street, the long side of those bends will basically have turned to slag and will blow out leaving a big round hole. Start wrapping about half way up the side of the engine staying away from the top bend by 4-6 inches.
Excellent article!
Perfectly done!
Factory was getting it right years ago with the y pipe 😀
3:28 Old school rule of thumb is to place the H pipe where the hottest part of the pipe would be if it was just a straight pipe. This applies to fabricators installing an H section into straight pipes. Discoloring of the straight pipe is evident due to overheating and is where the H should be located.
Wot is the best product to wrap my extractors in Thanks Andrew
I have found that on most late model cars & trucks with 2-3 catalytic convertors, the engines need a certain amount of back pressure to run properly due to the restriction of the catalytic convertors. I had a dual X pipe exhaust system installed on my 2017 Chevy Silverado 6.2L LTZ & found out the engine put out less horsepower then the stock exhaust system. That cost me about $4000.00 with TIG welding all connections & moving the 3 catalytic convertors.
loud pipes save lives
This is a fact actually. While I've seen they said many times in reference to motorcycles oh, I agree also with cars and trucks. Especially today when it seems like most people have their heads up their you know what. Half the people are either spaced out of their brains and Clueless, stoned in some type of way, or too busy fumbling with their phones, so they're not paying attention and next thing you know you're in a car accident. But when you're allowed pipes gets them out of their days and they hear you coming you are less likely to be in an accident. Well hopefully anyways.
I particularly think the whole noise pollution thing in reference to loud pipes is pretty much ridiculous and people need to stop being a bunch of pansies. Of all the things that can be offencive I don't think this is one of them especially when OK it may be a little loud but you can save lives because of it I think the pros outweigh the cons by far.
MDS I’ll mention this at my next mot, even though they will still put an advisory on it being too loud😆
Found the Harley owner.
This is tru.e I was riding my bike and almost got hot by a Tesla because I couldn't hear it.
What also saves lives is not riding in my fucking blind spot.
Depends a lot on the vehicle. Some mustangs sound better with an h pipe but like the year I have the 2013 gt it sounds more like a truck with the h pipe and has more of that hollow bellowing sound with the x pipe the way a stang should sound imo. I used to have stock h pipe but I’m putting a borla x pipe on mine with my borla exhaust. The sound of the x vs h has more to do with the axelback setup and type of exhaust system you have
I don't wanna hear a PEEP about exhaust "back pressure" as this explanation of the correct term called "scavenging" is clear and concise
now i get why the 96 VR6 Syncro has both a H and aY pipe in the system. (stock) .. neat video man old but gold (y)
I built a X pipe and a H pipe for my olds motor the h sounded way better than the x. The X sounded like Chewbacca taking a shit in my car!

@@Jonathan1003 Hey, wait a minute !!
I'M the Poster Boy for Tourette's -- you fuc*ers need to show some respect !!
On the other hand, if you happen to enjoy the LOW rumble of a big V8, consider that low frequency sound (i.e. BASS) is slower frequency, as in 4 cylinders at a given RPM versus 8 cylinders at a given RPM. Keeping the two channels of a dual exhaust system maximizes low frequency sound - deep rumble..... Just a thought. If you combine them with a cross over, well, that tends to double the frequency, greatly killing the bass.
A little something for those of you who consider a big engine sound music to your ears.
Awesome informational educational video experience Y'alls
Interested in your suggestion for my application.
Jeep 4.7L stroker, custom headers with dual outlet.
Option 1, Y-H-or X pipe after headers into single muffler?
Option 2, straight off headers into dual mufflers? (No crossover at all)
Option 3, H or X pipe into dual mufflers.
Interested in "best" scavenging method and a nice, deep, aggressive growl!
No Cat necessary as a "classic" vehicle.
Thanks 😉
I have a 289 in a 67 mustang, it makes great power from 5000 to 8000 rpm, the H pipe allows it to be driven normally below that.
Anthony Butera I have a 03 Dodge 3500 that makes great power at 2000 RPM... why I love diesel... we diesels get to use our peak power all day every day without blowing up the engine.
SilverStar Heggisist 😆
Nice car
Haha! A 289 between "5000 to 8000" rpm is between "dead and impossible"... I'd be impressed if it ever reached 5000 rpm - but going over it would almost certainly mean a 'leg out of bed'.
@@thenewviceroy
Not if built right. Mainly valvetrain beef ups. Oiling is not an issue for SBFs and the short stroke and good rod angle geometry allow it quite easily. Sounds good up there, too.
Suprised he did not mention tone difference. You will get 2 different exhaust notes from 2 different designs. I personally believe you get a deeper tone with a H. An X tends to be more hi pitched. I also believe the H sounds better at idle due to its design as well. I will only runs offroad H's on my Mustangs, just yes deeper is better. Ford runs the H from the factory.
jmfut I'm ready to buy a x pipe for my mustang gt. How much deeper is it with a h pipe?
SubieFL I would try and search on RUclips and see what you find. No Brainer is O/H pipe and Borla's. Just my 2 cents. My current Mustang is a 03 and I have a upload video.
Sorry but the note difference is night and day. If you want loud and Euro type sound go X. I honestly prefer deeper note of the H.
jmfut just listened to it and it does sound good! Mine will be slightly different because its a sn95. Decisions decisions 🤔
I love the sound of my beefed 350 with Hookers and an "H" pipe designed right at the end of the turbo 400 so I could still R&R the turbo if needed
Plenty of comments from a 40 year vet of the performance exhaust industry! First of all; Exhaust pipe diameter, You are correct about too big can ake exhaust pulses lazy- however; the addition off torque cones into the system , especially on a turbo-equipped car can solve this problem! Just be careful- the pipes get a LOT hotter doing this, so be careful about placement! Secondly; crossover placement or tuning. Optimum placement depends mainly on flow, i.e. cam choice, head flow, etc. An old school , but very effective way to determine where to determine crossover placement is to install a pipe on each bank, spray paint a line on them, and make some passes. where that line burns off (or closest to it as possible) is the best place! Hope this info helps! Doc.
Thank you, Mike!
I think it's important to note that not all x pipes are built the same, the ones that come together like the ones shown in the video are typically the best they are called Siamese x pipes because they don't have aggressive Angles of intersection. X pipes that intersect at near 90 degrees have been proven to show flat spots in the power curve when exhaust pulses literally crash into each other and cancel out almost any scavenging and disrupt the gas flow all together. The Siamese style allow for a pass by pull of scavenging vacuum with out having your pulse collide into each other. That's why most weld in x pipes with those angles cause power loses down low where the gas is moving slower and more likely to die off in a collision of pulses. They have less power loss in the Siamese style. I like to think of those as more like a window between both sides where they can pull on each other with vacuum, where as the other is like hallways that intersect and they have to try and pass through each other.
Thanks for the video! Great Information!!... What are your thoughts on putting an H or an X pipe on a 1973 392 International engine in a Loadstar 1700 Semi Cab? Or should I go with a Y pipe or just full blown Dual exhaust? What I'm wanting to do is make the engine most efficient at pulling a 30 thousand pound trailer.
*Straight off the header* 👍
engine masters covered this topic on a dyno for preformance
Link?
I trust this guy more than donut media. No 10 min explanation on everything else
Thank you for watching!
Excellent video.
Glad you liked it! Thanks for watching Daniel !
Would be cool to hook both up to an engine on a dyno and see the difference.
What would you consider high or low compression? 9.5 and lower= low, 9.6 and up= high?? curious as I am getting ready to build an engine for my Nova and would like to build the best exhaust to match. Thanks
Kayla Eliason did u ever build one???
Best if you don't try to go absolutely extreme...9.6 to 10.0 sounds like a good compromise. Assuming you will be running it on the street using pump gas.
Never heard any luck running higher than 9.5:1 on pump gas. YMMV.
I;ve found that back then, an H pipe used was a good thing. I put H pipes on a few of my big block Mopars and Pontiacs. I did not curve the pipes but left them straight and put the H in at 30" from the down turn of the exhaust from the manifolds. Used 2 1/2" pipe and Walker Continental glass packs. It sounded great and did pick up the performance a bit. This was done on stock non modified engines. Mopars were stock factory solid flat tap and the Pontiacs were stock factory hyd. flat tap. All of those cars were 4 speeds and road cars not drag cars. Great info video.
Just the info i needed, big tick here.
If I recall, when a twin exhaust was installed, it was installed without a H pipe crossover, then draw along the front half of your new exhaust with a high temp crayon, then beat it around for a coupla days. This would burn the crayon at a certain location on each exhaust, determining the points at which your crossover pipe would be installed. Of course you have to consider whether it will fit in the desired location. Been a while. Correct me if I'm wrong.
Thats what I learned too. I was wondering if he was going to mention it.
@@chrismoriarty3342 Maybe you and I are too old-school. We're just too used to having to learn these things the hard way.
I like the way H pipes sound.
Jeremey Allen Yeah same here. H pipe gives more deeper muscle sound while x pipe gives more raspier exotic sound.
I've got a 2012 BMW 550i xDrive w/ a 4.4L Twin-Turbo V8. It makes good power but sounds like a little girls electric moped... 🤣
I'm looking to replace the resonator with either an X-Pipe or straight pipes back to the stock valved mufflers, hoping that'll make it sound "meaner".
I understand the X-Pipe would give it a less raspy, higher exhaust note than straight pipe back to the stock mufflers... Would it hurt power much to just go with straight pipes, or H-Pipe replacing the resonator to get that DEEP RASPY sound, or do I need to go with an X-Pipe to keep from losing power on a small, Twin-Turbo V8?
Hi
I have a c200 kompressor w204
Is it a good idea to install a H-pipe by the help of a Y-pipe ??
Which would you recommend for a 2010 4.7L V8 with cold air, a straight-through muffler, and Superchips tuner?
I won't lie, I want performance out of it (nothing crazy obviously) but I have a camper and a boat that I want to tow and that's my main reason for upgrades.
Nice video! I own a 2014 Z51 C7 Corvette. Huge advertising budgets have been expended by the likes of Borla, Corsa, Billy Boat and Atak on their cat back pipes and mufflers for “performance power and sound.” Each one of these system cost thousands of dollars in parts and labor for what I read maybe only 2-4 hp. I would think that Corvette C7 engineers like Tadge Jeuchter have already engineered near maximum power into the power train. So my question is: can these aftermarket systems possibly be worth their cost? If not, why do many owners gravitate to them nonetheless? Your thoughts are appreciated.
status symbol tech perhaps ?
thanks so interesting, but what about true dual exhaust system?
H pipes and X pipes ARE true dual setups. If you're talking straight duals (no crossover), it's not as efficient because you don't have that scavenging effect that a crossover gives.
What’s left out here is the information on Pressure Waves and Back Pressure. Some engines are factory tuned with the back pressure needed to perform as tuned, no screwing around with the exhaust pipes. I.E., Porsche, BMW, etc. Same goes for highly tuned systems relying on pressure waves in the line. This is for guys wanting to make their car sound cool and maybe run better? Good info for legends in their own mind...
I have a 468 Big block with a 570 lift cam and a dual plain intake with heads that are ported and polished to match. I currently have headers with 2.5inch exhaust pipe true duals with flowmaster 40 series mufflers. I plan on changing to a 3inch true dual exhaust with straight thru Borla pro xs mufflers and I'm wondering if a X pipe would benefit me power wise and sound?
6.6 liter F250 with true dual exhaust. 2.5 to the twin Flowmasters with 3 inch out the side. Plenty of power and sound.
Lol there's 15 people who have no idea what your talking about in the dislike section!! Another excellent video I'd say! :-) :-)
Your Wrong it's now 200 people and really unless you have a race car your not going to notice the sound or performance HP anyway inside the car ?
Well explained.
What would be best on a 95 gmc 3500 dually flatbed with 454 ? Was thinking about running separate dual exhaust that ends at rear of cab but I don't know.
so what type of exhaust is best for a 2019 Mustang GT in addition to a CAI
Greg R x pipe
H pipe
H-Pipe, 2 MagnaFlow glasspacks, 2 Walker tailpipes, stainless tips.
Most bang for your buck !!
I wrapped my exhaust on my S10, what I ended up with was rusted out headers after a year or so. So, I definitely would not recommend it. Your results may vary.
Wrapped headers were a good .... short term solution to the problem of too much eat in the engine bay... as car became more aerodynamic, the heat became more of a problem.
Once the aluminum/ceramic - coated headers became widely available at a decent price, there was no good reason to continue using thermal wrapping (especially not on a street-driven car). As many people found out -a winter-driven car, with road salt, snow, rain etc. ... all the moisture would collect inside the wrapping and hold th moister in close contact with tubing headers, exhaust pipes.
Aluminum/ceramic coated headers ... are much better at resisting heat damage as well as (when coated inside and out) ... they send most of the heat to exit the car... instead of collecting and heat soaking (steaming up) all the moisture.... yes, rusted out headers and exhaust are a big issue when using thermal wrapped exhausts.
Yeah it’s pretty obvious you wrapped a metal not meant to be wrapped. I’ve had wrap on my headers for years and show absolutely no signs of being rusted out. Learn from your mistakes.
That and they have heat wrap sealant just for that reason you just stay it on thick and let it dry
Hey question I bought long tube headers for my 2013 Dodge Ram 5.7 hemi and 2 Flowmaster super 44 . Because I want do dual exhaust with 3 inche pipe do I need a x- piple . Yes or no
@summit Racing --> I have an 2005 Jeep Grand Cherokee V8 4.7L with the original configuration as shown in the 4:03 minute. Do you think it is the maximum power configuration I can get? Thanks for answering.
With my stock motors i like to run two 2.25 inch pipes into a flowmaster y pipe then dump that into a 3 inch single pipe to a 3 inch in and out muffler. My fuel mileage goes up as well as my top end. just my .02c..
I'd like to know more about two into one exhaust im running duel 2.5" that's goes into a single 3" and that made more power on the dyno then a twin 2.5" system and I personally think it sounds better haha
Good video!
im looking for a way to bypass the catalytic convert but only sometimes. is there some kinda pipe that has some kinda valve that can move back and forth?
How do you decide what diameter exhaust pipe is best? Obviously I want the biggest pipe I can without scavenging velocity falling, but how do I measure this?
As a rule of thumb 1" per 100hp per cylinder bank, however a little more may (or probably *will*) give more power (but be louder). So 500 hp = dual 2.5", however lots of systems are dual 2.75" or dual 3" for such an engine. The S550 Mustang GT runs dual 2.5" for 420hp from the factory, for what it's worth; the old Shelby GT500 ran dual 2.75" for 600hp from the factory. For a racecar you could just go as big as possible, for a street car it's about if an extra 10 or 20 hp is worth all the noise.
thats cool... speaking of cool, i had a 1995 gmc safari with a 4.3 liter and when i put a dynoflow 3 inch otorhome muffler on it it ran cooler engine temps due to the easier breathing system and it never had the proper fuel to air ratio it would run richer cause it thought it never reached proper factory engine temps .. i wished i never put that muffler on it and went with a more factory/restrictive one
@@TassieLorenzo 21/4 " seemed to be a good choice for my 289 it made between 325 and 350 hp...set up the way it was it pulled strong all the through 100 mph. And got to 100 pretty damn quick.
what about a w and z pipe?
Lol
U, v, or j?
I go down to the A&W to smoke ze pipe, eh !??
derp, derp,derp,duh🤪
Which pipe would provide the best performance for the Ford Mustang 2018 stock 5.0GT engine.
And thank you for the video
Great video, thanks for sharing
Thank you for watching, John!
what about no pipes?
State and local noise laws.. At least on the street. At the race track a uncapped xpipe or header extentions(depending if you have headers) is probably closer. I had a 302 ford years ago and tried an h and x pipe and the x pipe was faster on the drag strip and was a lot quieter around town(2.5 type 40 flowmasters and a 2 .25 dual tailpipe) also removing the 100ish lbs of exhaust and running made 0 difference vrs leaving the full set of x pipes on.
basically like putting oversized pipes. More of a drag strip thing. your engine might just kill it's valves on a daily driver
Scootermagoo, do you know why exhaust pipes exist? Since you figure it is just noise ordanence laws, maybe put a hose from your exhaust into your cab and drive around.
Travis Root I think we can be friends 😂😂😂
retcwby - for that raw sound
that reminds me to get my pipes cleaned
Lol, time to call mom again 😆
Thks for the info !!
Great video. Thank you.
