Long Tube Header DYNO RESULTS!!! 392 6.4L...
HTML-код
- Опубликовано: 15 сен 2024
- 6.4L 392 Scatpack adds kooks long tube headers and jumps on the dyno to see how much HP & Torque was gained. In this Ted from Jannetty Racing talk about the performance gains adding long tube headers to a 392 v8 hemi. All of Dodges SRT models have mid length exhaust headers/manifolds so the performance gains going to long tube will be very interesting! Are Kooks long tube headers the best for the 6.4L 392 V8 Hemi? Well lets see how it does on the dyno.

Thank You Everyone for the SUPPORT! You Guys are awesome
Hey after them videos can you do a 392 shaker that can with mods and upgrades and show few little rev burnout like any just saying so I can understand when I do my challenger thanks for that video man
What was your Rwhp?
Hey R/T good videos bro Thanks a lot for bringing more 6.4 content.
It helps tremendously.
Know I have a question. Would an x pipe hurt or benefit my scat pack and can you elaborate on that please. Here a run down of what I have: kooks long tube header cattle’s mid pipes. And no mufflers or resonators I’m straight pipe. he’ll cat intake tuned WITH HP TUNER.
Thank you and I hope to hear from you soon.
Can you take a diablo sport tuner and adjust the A/F ratio and gain more hp or do you need an unlocked ECU?
What ended up being the final cost with everything done bolt-on
No one is doing content like you doing ... Very informative and this dyno guy is really a gem
Thank you very much! Def learning a lot. Yah Ted is the man, he really knows what he's talking about.
@@RTLife yeahhh 👍👍 stay out of clickbait life .. 😂 i think this is the only channel without clickbaits
@@beowolf9991 I tried to talk R/T life into getting a hot scantily clad "Spokeswoman" but he said NO!
@@RTLife I went there with my first car a year and a half ago and he's done 7 of them for me so far. He's a keeper as we say.
@@pmac5386 lol thats cheap way to sell the content like that 😂 ... Its good without women in it because we can focus on content not on boobs
The guy is a genius! Thanks for introducing him to us R/T LIFE.
hahaha he really is super smart. Def knows his cars! Thank you for the support
I never did business with a speed shop where the owner (Ted) was always willing to sit down and explain the real hardcore nuts & bolts of how and why these mods work as well as what to expect.
FYI: Jannety's Dyno is made by Superflo and is state of the art for generating real world WHP numbers. Anyone who operates a dyno can easily change the settings (for example the "smoothing factor" ) and get fantasy land results. This Scat Pack might run in the 470's or higher with just a click of the mouse. Ted's as honest as the day is long.
P Mac that’s what I liked about him. I ran mine at the dyno day and with K&N intake long tube headers and catless midpipes and no tune yet it made 421hp and 449 lb/ft toque.
exactly! Ted is all about honestly & giving out real information. So much BS info out there.
I made 444.7/493.3
Ted is the man! Internal timer, butt dyno, and real dyno? Not to lose sight of the 20/20 gain, that's tremendous. The ET gains were better than I thought too, I was thinking about a. 25 - .35 ET drop, but .40. 👍🤘👌🇺🇸
Yah the performance gains are big time. On the track it would be much stronger car!
Teds dyno is the real deal I've had 5 cars done there and this is the first time he mentioned the ET gains on my Scat Pack. I drove it right after the dyno and it pulls like race horse thats wants to go faster and faster.
@@pmac5386 I don't know if you remember but I'm the torque junkie. I'm so happy you were able to get a square hp/trq gain.
Following this build to see what mods the 392 likes so I can put them on my Scat Pack Charger.
Nice - hopefully this is giving you a solid idea of what to expect ballpark wise.
Jose Vega YES!!!!
I knew when I gave Ted the car to use as a package build project there were going to be truly honest results both good and bad. If we knew all the answers we wouldn't be doing this. lol
@@RTLife sure is! Keep up the good work Brother!!
come have a look at my build
I like this 392 content. I started watching your channel when I had my R/T. I upgraded to 392 Daytona .
Thanks man for the support - I like having this content up as well. Makes the channel a little more diverse. Keep on enjoying that 392 - they're a lot of fun!
Honestly this should be a package someone should offer. This would be perfect for anyone wanting more power out of a 392
Agreed. I think he is looking to package this up at some point @JannettyRacing
I would buy this package ASAP .. something about a 392 able to make 500plus hp is awsome
Is this package available?
A great veiw and a wonderful opportunity for all to see the results of modifications, and affects the horsepower of each mod done! This is the rite way of determining true gains in a controlled environment!! That is a nice car and a great guy doing the job! Awesome content! 👍✌!
Agreed! It's def cool seeing how these mods improve the performance of the 392. Once this thing has forced air, LOOK OUT! Thank you for the support - def appreciate it.
I'm shocked how powerful these 392's are and how marginal the gains are with bolt on mods.
Love this step by step process. Makes you appreciate the modding process and those that bring it together with a nice little tune.
⭐️⭐️⭐️⭐️⭐️👍🏻👍🏻
It's super interesting right?! I'm really glad this build is happening, certainly learning a lot about the 392.
My 2014 Challenger was honestly less challenging to mod and the 5.7 had solid improvements with mods. Maybe they left a lot more HP on the drawing board-these 392's are almost maxed out right from the factory.
Such a Great build and the numbers going along with it really puts things into perspective. This has been missing from RUclips, anywhere really. Great work Bro!
it's nice seeing mods go on & a dyno showing it off! Thanks man - def appreciate it.
Good info when I run out of the warranty it's good to know what needs to be done keep up with the good videos always great content
Glad this info is helpful. You will enjoy squeezing more out of that mopar when the time comes!
I know-I know my warranties voided. I do have a lot of faith in the Hemi engine and confidence in Ted knowing he'll warranty and or replace/repair anything Jannetty Racing has done.
I been going to the racetrack best been 12.66 112.84 only have 4000 miles on it can't stop spinning off the line
Nice. I like these dyno videos. Helps me not waste money on parts that don’t help gain power
Yup - that's the point. Mod & give everyone realistic expectations on how it influences performance.
Car sounds strong 💪🏻 nice gains
Agreed! This 392 is running strong
I test drove it right off the dyno and that lowend torque pull hard!!
As a mechanical engineer and a very long time car guy FINALLY I have someone who has the FACTS & INTEGRITY to use them to explain to all levels of car guys. I just found the channel but I'm interested in what I can do additionally that actually works to boost the HP on my Charger SRT without actually spending all the coin.
Loving the 6.4L hemi content. I have a 5.7L in my truck currently. Just bought a 6.4L doing the swap soon.
Let me know how the swap goes - sounds like a heck of a project. Thank you for the support
I'm still big fan of 6.4l shaker 392 because the performance mods for the engine and the looks. Plus if I get one upgrading the tires suspension headers, Manifold and exhausted pipes and the throttle for. The 392 shaker I'm putting a dodge demon throttle body swap with the 6.4l still can't wait
Go for it you'll have a blast!
Let me know how that throttle body works out for you.
OK I will let you know when I can
This vide proves my point... Bmason tries to tell people that hearders dont gain you any power at all on 392 and I have respectfully told him that there is definitely some gains to get from them with a tune..... Great video.
The gains aren't earth shattering but there are gains & as you continue adding more mods they will prove to be worth it.
@@RTLife Exactly.
My ls3 camaro went from 375whp stock to 435whp with cai long tubes and a tune lol 60whp. Just shows how amazing stock the 392 is. But man the ls3 is so held back by its exhaust and intake. Id be pretty pissed spending 3-$4,000 for 20whp
He needs to straight pipe the rest with a nice big X pipe. Best sound ever
The thing would sound so damn mean!
Very knowledgeable guy...Every time I see you upload I just got a watch it 😎Glad I did.
In person Ted thinks nothing of spending an hour or more educating his customers on every facet of what he's doing on your baby.
P Mac That’s an awesome thing.My customers love it too when I explain exactly what’s going on with their vehicle when it comes to repairs.
Yah he really knows his stuff! Thank you for always supporting the channel. Def learning a lot along the way
R/T Life you’re welcome 😎👍
great video. It is good to have the numbers backing him up and the acceleration seems really great
Thank you - yah def interesting looking at the dyno charts & comparing. I would say a decent pick up throughout the RPM band.
I'm drooling thinking about doing this on my scat pack challenger 😁
the dyno gains don't tell the whole story - this 392 def improved performance wise
@@RTLife I'm ready hahaha
Awesome! Was hoping to see numbers like this. 👍👍
This thing is def putting down some power! Thanks man
Yay! Great explanation of power! It's about time!
Thank you - I appreciate the support!
“It’s bad ass right out of the box.” 👍🏻
Agreed! Def a great performance engine
Best video in months! Keep this content coming bro!
Thank you! Def learning a lot of modding the 392 now. I appreciate the support
That’s some great gains 👍🏽
Agreed. This thing is def a monster!
Bro-it's not just the gains this 392 pulls like an animal. It just wants to go fast er and faster now.
It’s comes down to money though....a set of green catted kooks headers is almost $3000 plus whatever install was....for most people that is definitely not worth it....e85 tune will net you at least 20whp or more at 1/3 of the price. Just my 2 cents
Yah the cost is def expensive for the 20whp. That being said this build is getting forced air so all these mods are needed to maximize the gains down the road.
two cents always welcome. I got 30-40 Whp on my LT4's for same $$. Unfortunately here in CT the only E85 you can buy is Ignite Race grade fuel and its expensive. The only saving grace with h LT headers is the roar is amazing (if that floats your boat) LOL
I purchased my Kooks and cats for 1650, install is easy enough to do yourself from the ground via jack stands with minor mechanical skills, and doing some research prior.
JazzBee greens cats or regular cats? Regular cats are half the price of green cats
@@slomango7927 HF, the greens were 300 more. HF are rated to 650hp crank, Green up to 900
Excellent video..... def helps with future purchases for the scat!!!!
Glad this video is helpful. Thank you for the support - I really appreciate it.
Big respect to you brotha. You're super informative. You very detailed and patient with way you explain things....Im in the MOPAR community myself and I've been learning from. Blessings to you😎 #moparnocar 😤💪🏾
My scat pack future mod list 2018 challenger scat 11k miles.
1) AFE momentum GT intake- 500$
2) bigger throttlebody- 250$
3)bigger wheels and new tires- 2000$
4)borla S type cat back exhaust- 1500$
5)high flow cats- 200$
6)long tube headers- 1300$
around 6,000$ plus installation costs for headers and exhaust system. Does this sound like a good game plan?? im afraid if I just buy a procharger my car will explode so I was thinking keeping it NA and letting it breath better is the route. How much HP should I expect???
You're not going add a ton of WHP with those mods, but it will be a much better performance car for having those. Probably a gain of 30-40whp depending on the tuner.
Old Video, I know. Last May had my 5.7L Challenger at OST Dyno for a 180 degree Stat, Their "Rumbler" cam install, along with Kooks Long tubes, High Flow catted midpies, unlocked PCM and Dyno Tune. Car went from 350 WHP (Stock except Scat Pack 1 PCM) to 434 WHP!!! Going back this year for the larger Catted mids, an OEM Hellcat cat back, with the Active Exhaust Welded open, Stall Speed converter, QTP Electric Exhaust cutouts, 1 piece drive shaft and differential brace. Forgot to mention before it went to OST last year swapped out the Open differential for the 3.09 LSD, for my 8 Speed. Might look into a 3.90 set up next.
That is a big time HP jump! Were you able to run it at the drag strip? Sounds like you have a solid plan for the build
I wonder how much a 5.7 charger with the stock 392 full exhaust make on a dyno
Only one way to find out!
@@RTLife thats true I'm out the loop RN lol I maybe the first because I don't see any dyno video's on it besides a 392 and they already have Lt installed so can't see that
@Lucho S I got a 2016 I wish I did have that
My man
You on IT
Like a HORNET
If I keep my scatty, this mod is a must 👍🏾
You will enjoy the increased performance! Those 392's already can move to.
R/T Life yes sirrrrrrrrrrrrrr
I got an 18 scat Chally I went with the Stainless Works with Redline 3 inch exhaust with long tubes with Diablo I3 and jammer cold air intake. I enjoy your vids you give information of whats good and what might not work. I bought the jammer cold air intake watching one of your older videos of your talking about it with your blue Charger.
@P Mac your car build is starting off great can't wait to see the next video
Yah this is def a cool build! The 392 really is becoming a beast.
What kind of tune did you do on dyno? Spark advance, timing?
That is a question for @JannettyRacing
you pretty much hit it on the head plus FAR and somethings I honestly don't understand.
I know this is a different topic, but I did a 330 mile round trip today. My RT Road and Track only has a CAI, resonator delete and glasspacks in place of the mufflers. I got 26.7 mpg average round trip. One stretch in between exits that was all flat, about 40 miles I was averaging 32 mpg according to the computer. Is that normal?
4 cylinder mode is wonderful for long trips lol! yes it's def possible. I've been in the mid high 30's on wide open road cruising 60-65mph. They can haul ass or sip on gas - def makes these hemi's a must have!
Is he also tunning the car are just data logging?
He is tuning as the mods go on
Do u still get gains with out a tune. 🤔🤔🤔
392 w/ long tube headers no tune on the same dyno ruclips.net/video/n6V2Ign44wY/видео.html
The torque gain was significant with the long tubes. I can really feel the difference. I’m am going to have Ted tune it this fall and see what we get.
Lol idk if a toque gain is good. Considering the car can’t even hook up as it is from dead standing
Hey were y’all able to get to the headers without jacking the engine up? My headers have a bad gasket that needs replaced and I just can’t get to the bolts.
The engine didn't need to be Jacked up for headers.
So I assume the total cost is
- Kooks headers
- installation
- unlocked PCM
- tuning
Give or take $3k???
I have to ask - 3-4k is likely the ballpark
What size kooks headers should I get for 2020 wide body scat pack shaker . 1 7/8 or 2
My Scat is bagged, so I'm wondering if long tubes will get in the way of airing out? It almost sits on the ground now, and I've heard these hang pretty low...🤷♂️
This damn bee making me wanna compare a 6.1L SRT-8 already!!! Sounds really good with them long-tubes in there! 🥵🥵🥵🥵🥵🔥🔥💯💯💯👌🏾😈😈😈😈
Long tubes def give it a nice deep rumble!
@@RTLife Hell Yeah!!!! Sounds the same as a Hellcat minus the whine!
Looks like I know my first 3 mods thanks for the video man helped me so much to choose what mods I'm roll with
Nice - glad this was helpful. I appreciate the support
If you're not a Dodge ambassador at this point, you should be. People like Demonology are great, but most of us are are running 5.7s and 392s.
Thanks man, def appreciate it.
So what was the before and after dyno numbers with the long tubes?
392 all day long baby!!!!! Still would like a Hellcat Red-eye though...😁😁😁😁😁😁
I hear you on that! Those redeyes are so damn awesome.
Do you need to tune the challenger after putting on long tube headers because I want to do it myself to my challenger but want to do it right
You will likely walk away with a check engine light without tuning it.
I am planning on having Ted tune my scat this fall. I hope what he learns here with this wide body will make it easier to tune mine.I have a few good pulls on his dyno to reference. I will let you know when it’s there if you want to video anything.
You will not regret it. My RT pulls like a SOB! He's def a very knowledgeable guy. Let me know what you're planning on going, I will see if I can make the trip.
My friend, is this with tuning? Or is it simply bolting on and going? I know from the factory these cars are looking for 11.8 AFR @ WOT, so increasing the air brings the AFR back to peak 12.2-12.5. I am curious if this is tuned in or not! Thanks :)
So... if you want an easy-ish 450whp from a 392; get long tube headers.
Basically yes.
If you follow this build series starting from the baseline video it's been tweaked and retuned along the way in addition to the LT's.
@@pmac5386 I have followed the build... the tune (which I found surprising), intake, and 92mm TB did not add much in the way of power on the dyno. Go back and look at what Ted has to say... What was gained prior to headers was all more or less under the curve, which leads to enhanced drivability. The headers, which I'm sure Ted tuned for, are the first mod in this series where legitimate power has been added to the car.
So long tube headers require modification like cutting the pipes to make them fit since the OEM is so much shorter?
i put long tube headers on 2005. 5.7 300c, and only gain is between 2500-4000rpm, max speed is the same 250km/h, in meantime i set exhaust -no cats, suitcase replaced with full free flow muflers, and rear muflers too, same result, no improvenment on max speed
What was the gain in power? I don't think any exhaust work will help top speed
in my country , is no dyno for awd, so i do not know power gain , car is faster to 62mph, from 7 sec to 6 sec, and there is some noticable gain on 2500-4000rpm , but max power is not changed to be noticed
and i tried to buy some good headers but for awd, nobody works it, so i went to best local exhaust master and they made it with big pain in their and mine ass
what would it do if QTP cutouts were added? that would completely open up any restriction in the exhaust.....I added QTP's to my 1320, my "seat" DYNO says it made a difference....or it might just be the the dominating sounds that makes you feel like your going faster...
Nice to actually see the results of a header install. I don't agree the factory manifolds are mid length, hey are shorty's, mid length are longer than that.
Huge rebates now on Hellcat and redeye I guess due to to C8.
Yah I saw Dodges new offer - def a lot of $$$ saved
The dealer I bought the scat pack from just text me $7170 off Hellcats $7970 off Redeyes.
@@pmac5386 maybe part of it, but a stock hellcat is the same MSRP as the C8, and two totally cars and categories tho
They gotta sell them now (August) or they're going to sit on the lots into 2020 with dealerships taking a big profit hit to sell them. A new 2019 is going to be worth thousands less than a new 2020 when it rolls off the lot. A savvy buyer will use this knowledge to negotiate thousands more off on top of rebates. With these rebates, it's definitely a good time to do some haggling
How much can I expect to pay (ballpark) for these mods on my 392? Parts/Labor
Honestly, the RT although at a huge numbers deficit responds to mods better. The Scat is ALREADY great as it is and not as restricted as the RT.
yah you get a better bang for the buck doing bolts on with a 5.7L. The 392 has great pieces in place as is - so not much room for bolt on gains.
Here’s the thing though you need at least 6/7k to get somewhere near the scats hp I got lt headers intake and throttle body and exhaust and I’m at 470whp on the mustang dyno no tune for 6k you probley can get a rt to 420whp
Sorry auto guys that chally sounds amazing with the manual. I hope it’s a manual because it sure sounds like it.
I don't own the vehicle it is not my vehicle but after watching other videos let's just say it gets dynoed in 5th gear
It's a manual - it def sounds awesome!
I just installed 2” Kooks headers on my 6.4 Hemi, along with a ported intake, and 87MM TB. I had previously installed a Comp 274 cam. Hit the dyno after the headers and ported intake today and picked up no gains. Headers and Kooks mid pipes into factory mid muffler. Could the mid muffler be holding the power back? It didn’t move any more air today than prior to headers and ported intake.
Did you need a tune after installing the new long tube headers.
Yes - After every install a dyno tune was done.
Very solid and realistic numbers for longtubes on a 6.4 you don't make big power but there are clear gains had
I really like the fact that it was a square gain 20 hp 20 lb ft. I know a lot of people are more impressed by the horsepower numbers but I like torque too
The overall performance was drastically improved even thought 20/20 doesn't seem like much. Def a learning experience though & it's cool to get realistic numbers after each mod.
Great video bro. Hope you’re doing well
Right back at you buddy, hope all is going good on your end. Life is great on this side of the computer!
What size headers? 1 3/4" 1 7/8" or 2"
Thanks
I believe 1 7/8
Thank you.
Can you do this with a stock 5.7 RT? It would be nice to see if you would get similar or better results since the 5.7 is so restricted compared to the 392.
I went from shorty headers to long tubes & gained about 10whp throughout the curve. It would be interesting to see stock vs long tube headers on the dyno. The 345 exhaust manifolds are brutal so it would be a much bigger bang for the buck upgrade.
You have a very similar Challenger to what I'm looking to order in 23. Granite W/B manual Scat. I want the bee stripes on the rear, though. I won't do anything to it except the Hellcat Lower airbox with light inlet and exhaust until the warranty runs out. I like the Shakers, but they really seem to be a whiz-bang cosmetic performance hit that you pay for. I thought about the T/As but they lose the heat extraction vents. Everything I've seen indicates that hellcat intake with the standard heat extraction venting hood will give the best performance. Aftermarket CAIs don't seem to perform any better than the HC intake.
Question, I have a 17 Charger 392 with catless mids, CAI, 87MM Throttle Body, straight pipe, and it was just tuned to 481 HP and 488 WRP. Why is that scat not pulling similar numbers? Just curious.
Some shops use different correction factors. It's really just supposed to measure gains. I'm sure if the both of you jumped on the same dyno, they would be similar in power/torque.
@@RTLife thanks for the reply. Very good information to know.
I have got to get me those headers!!!
It will def make a solid difference in performance.
Advice-find someone who can powder coat them. It makes a HUGE difference on how much cooler they run. I had Ted put coated LT on 3 of my other cars (no joke) it's worth every dollar.
Too much to understand for me. Can you tell me how much HP or Torque the headers improved
Hey everyone I'm going to purchase a 2017 Charger, my question for everyone is should I go with the Scatpack, or is the SRT worth the extra money?
Depends on what you're going to do with it. SRT if you ever want to track your car. Scatpack if you daily and/or drag.
@@RTLife I'm not planning on tracking the car, it would be a daily driver.
A scatpack is a better fit. Costs less and has what you want, the power.
Back in the day, muscle cars would come with "mag wheels," ie, Magnesium wheels. Has anyone put any of these light-weight wheels on the rear end to see how much power loss you can recoup?
If you did air intake and long tube exhaust without the throttle body do believe the result would be beneficial or are u going to do damage without the throttle body change?
Can do those without the throttlebody upgrade no doubt about it. Yes you will pick up a nice amount of HP with intake & long tubes alone.
You did long tubes and I can only assume high flow cats? How does that effect your emissions in NY? I also live in NY and was looking to do this, but everyone keeps telling me ill fail emissions.
I haven't had any issues passing emissions
I have a question. How do mods like this affect the longevity of the engine without a blower or nos? Because I do want to add headers, exhaust, intake, tb, and stuff like that to my 392 but I do plan to keep my car for some years like 6 years or more.
ok good question-most of these mods to shown to date put minimal stress on the internals. Although a bad tune could do some serious damage. Hey they're machines and things happen. This scat pack had a faulty PCV connection/valve with 600 miles on it and blew smoke like a diesel locomotive. Forced air should not exceed the limitations of the low end (tread carefully) and NOS is a big no no!! It's for hardcore professionals and they blow engines all the time.
If you keep it n/a you'll be just fine. Blowers/Nos add a bit of stress onto the engine. Headers, exhaust, intake just optimize the air going into out of the engine. Tuning will make sure the air/fuel ratio is on point so you're not running rich/lean & potentially hurting any parts.
I have over 50K on my Scatpack and I drive it hard. I have long tube headers since December. I have not had any problems.
@@RTLife Ok, thank you because that's been on my mind ever since I gotten it. ✊🏾
@@pmac5386 Yea, I'm not going to be running nos. Not something I want to mess with. Plus I'm not doing anything serious to even really need it. But I greatly appreciate the advice. 👌🏾
i’ve been waiting to pull the trigger on kook long tube headers in my 392, but curious can i stay stock with cats? or do i need a new one?
Maybe a dumb question, but did you have to tune the car once you added those upgrades?
So what mods have been done so far? CAI, throttlebody, headers,high flow cats?
Yup
Did they state piping size? Did they use the 2" or 1 7/8" kits?
What kind of dollars are we talking about for just the exhaust??
Depends on which brand you decide to go with
Nice gains!!
Agreed. Def worth doing!
So did the hellcat throttle body end up gaining power or did it not help?
How about a custom intake manifold that'll work with a hell cat throttle body???
Once this build gets forced air the gains will really show through!
Is he also adding a 93 tune or is this just the stock tune and bolt ons?
sounds amazing.. What was the mid pipe and mufflers? Anyway, I plan to get a Magnum srt8 sometime this summer and would love to throw on some long tubes on it
This has long tubes, high flow cats & stock mufflers/resonators on it. Def sounds good. You're going to love having a 6.1 SRT - awesome rides.
That’s it, I’m getting this car.
You're going to really enjoy having one
Will the old 392 exhaust manifolds fit on a 345?
Yes - I've heard of a bunch of 345 owners do this. Basically a nice cheap way of getting shorty/mid length headers.
Awesome. I’m thinking about a 392 intake and header swap on my 5.7 with mid delete. Good to know they fit.
Question, when you guys put the kooks long tube headers on. Did you use the stock mid pipes ?
Great question - I have to ask
Stock mid pipes wont' fit with headers.
What do you think about exhaust cutoffs
Sound great but from what I heard they're not the best for performance
Iss there anyway to run longtube header with cats still on just concerned with noise on cold start and how much would keeping the cats restrict the flow? Is it worth it? If its only a couple hp increase from removing the cats id rather not i work at 2a.m and live in a quiet neighborhood is the reason for question. Thanks
yah I have high flow cats with my long tubes - the only time cats become a restriction is when running high boost.
@@RTLife good to know! Would a good catback exhaust make a hp increase? Or does dodge have it down pretty well? I have. 21 widebody sp
@@RTLife i plan on getting 650 cc injectors running proflex commander flex fuel kit for e85, longtube header(not sure which are best yet) and jlt intake and tuning with jaygreen or maybe an actual dyno.

Yes this was tuned after install

I had an 09 srt8 challenger...mine did the same once, I disconnected the battery for a bit, re hooked it up...problem solved. I would try that first as it's free.
@@alwaysreturnNurgirl what else could it be I could drive for an hour and it would bearly start to try to get cool on passenger side
Can I have those factory manifolds for my silver letter charger? Just thought I'd ask.
I have no clue what they ended up doing with those manifolds - the shop is in CT.
@@RTLife I was just joking man. Imma put kooks on it just like you guys did here. Stainless and borla attacks
I wonder if improvement like this will be almost the same on a 2017 Jeep srt
I don't see why it wouldn't
R/T Life I hope so just got stainless works catless headers.. going to be paired up with my borla atak cat back.
Did I miss something? Was the horsepower gains Actual number mentioned? Also, did this also include a car that had an Airraid box and Hellcat throttle body? If so, the results would be a little skewed over just adding headers.
Was that without a tune?
No this has a tune adjustment on it.
did you change out your whole exhaust system or just added the long tube headers?
just added long tubes & put high flow cats. Stock after that
@@RTLife Ok i am about to do the same. What throttle body did you go with, and i am getting the hellcat injectors. no cam mainly bolt-on and tune. How much HP will i get to the wheels you think?
@@RTLife how much louder is the car with the long tube headers?
