Great video bro you went straight to the point👍🏼 Thanks I'm definitely going with the flowmaster on my fbody camaro💯
The old man at the muffler shop highly suggested magnaflows , said the high school kids usually go with flowmasters
The old school guys at my local muffler shop suggested magnaflow for my car. It definitely sounds good and isn't overwhelming
@@pguy5 they sound pretty darn good 👍 350 small block carbeurated with long tube headers
I go for the more expensive Flowmaster , HP2 laminar flow with the packing inside
@@pguy5 anything but flowmaster mufflers I never liked those things
Seems like the particular guys recommend Borla.
I have a Magnaflow on my ‘99 Yukon. Has a nice throaty idle and throaty acceleration. Nice and quiet inside the cab. Finally rotted out after 19 years so I purchased another one. Great sound!
Rust Belt?
@@jesusjimenez3766 Nope
no need for loud background music..
Did you make the video?
@@SilentKnightVII not your business
I agree
Totta
Love the explanation between the flowmaster vs magnaflow. The exhaust depends on it.
The exhaust depends on what?... hype and BS or truth? The truth of the matter is, Flowmaster are rated at the bottom of the barrel when it comes to high performance mufflers!
@@Anarchy-Is-Liberty thank you for saying that that magna flow Is it straight through flow design It's going to flow way more CFMs than that flowmaster ever will It's just a clickbait video
Simple clean explanation. Thanks! I understand that the magnaflow would sould better on inline 4 Honda's.
Spelczech, bro: I use it every day. But let's really distill this down. The flowmaster is not marketed for its cfm capabilities, but its tone. I translate that into... people wish they had a v-8, but they bought a flowmaster instead. Or... they do have a v-8, and would like to pretend it's a 13:1 track car with a great big cam. When they put a tip on their system to boot, I dub that a 'fartophone' - I can hear their fakery coming a mile away.
One of the peculiar things about this business is even for the few companies that will flow test their mufflers, flow differs quite a bit between offerings with same pipe size. I have a reasonably built 355 with dual exhaust, and for velocity reasons I won't put in 3" pipes [I stopped at 2.5"] but: in the majority of manufacturer offerings a 3" muffler is what works if I want to stay away from track type noise and get every last bit of power near redline. In my case, I found dynomax's 17748 [a 2.5"] worked for my application and stayed near a loss free system for probably 95% of rpm range - but I could get everything with the 17797 [a 2.75"]. It will rev to 6500 either way without complaint, and doesn't say "bust me" to any cop car with a window cracked. I like that.
Especially sounds better on small displacement engines, but all engines sound better with Magnaflow compared to Flowmaster. Performance gains naturally are better with the straight-through Magnaflow, and that's the real reason to get one!
I have a Flowmaster 50 Series Delta Flow on my 2020 4Runner and it is perfect sounding. Nice back ground rumble at idle, nice mechanical burble when I accelerate, np drobe on the highway. This is the 2nd vehicle I've put a Flowmaster on.
The first was an '09 Toyota Matrix with the 2.4L. Did a full custom 2.5" exhaust with an 80-series. She was loud!
Pretty damn happy with my 18" Magnaflow + resonator deletes on 2019 Silverado. Beautiful low growl cold start and accel tones, not obnoxiously loud, very little idle speed drone. Paired with KN cold air intake its butter. No tin can noise like with Flowmaster. I Just want the same tone but a tiny bit louder. Considering Magnapack glasspack, or Cherry Bomb glasspack.
I've got the same sized (5.3l) engine in my Envoy. I live in a state where they'd never check for cats, so had them 'fixed.' One of them was partially clogged, so getting them replaced with pipes was justified 😉. It's a cheap (can even MAKE you a few $hundred) and easy way to free up a few more horses, nearly 1mpg, and add more volume to your Magnaflow. I believe your exhaust is nearly identical to mine, and the cat-ectomy would definitely up the rowdiness factor of your 5.3 a bit, and gain you at least as much horses as your magnaflow. Mine didn't get a check engine light, yours may but can easily be remedied with $10 O2sensor extenders (or a tune). That would be your best bang for buck option, as it would be cheaper then switching muffler, and would free up more back-pressure, whereas you can't improve the backpressure by replacing Magnaflow with an inferior brand.
I need to tone down my hemi ram for cold starts.....my eBay exhaust has a through style muffler but after 2 years it's pretty loud and drone can be loud. I am thinking Large magnaflow to quiet things down....
Very informative video. I will definitely be getting a Flowmaster.
i have watched several opinions on youtube, yours is the very best! thank you,,,,,,,,,,,,,,,,
I went with Magnaflow on my 5.7 V8 Tundra and I’m really glad I did. I did not want an aggressive sound. I wanted just enough kick to tell you a real V8 is under the hood. I got exactly what I wanted.
Not to mention, you got a better muffler for your money, and they make plenty more horsepower than the Flowmasters do!! Good choice!
Which MagnaFlow did you go with ? The Rumble by chance? I have same truck about to put exhaust setup on .. thanks!
@@Hmmm7512 Honestly, I'm not sure. I told the muffler guy I wanted dual exhaust, not loud. Magnaflow was one of the choices and that's what I got.
Got a Super 40 Flowmaster on my 2001 V6 Sonoma and it sounds a whole better than stock, and it actually has improved the mileage and not to mention Flowmaster is the least expensive compared to the Magnaflow or Borla.
Good stuff man. It’s all about fitting your needs.
Flowmaster js made in china now , magnaflow usa and better stainless steel
@Johnny White Cheaper last longer, still have the Flownaster 40 since 2005 on my daily driver
I have a Chrysler 300 v6, it's not an 8.. but it is what is.. What Magna flow do you suggest I run with? should I also do the cold air intake as well?
Got a 6.0 silverado 1500 vortecmax..already pretty loud. So now I need to figure out what to do as I'm buying a whole new exhaust system for it. My brother says magna but Flowmaster is $50 cheaper as far as the 2 im looking at
Your comment at the end "if you have a v8 just get the flomaster". I have been going back and forth with either a flomaster, borla, or magnaflow. Thank you.
I agree, they should have a good muffler on from the factory!👊
Luv my Flowmaster Flow FX Straight Through muffler on my
Ram 2500 4/4 Hemi 💪
Got a ctsv with a 6.2 lsa with headers and 3’ system , tired of the drone from the bullet resonators. I love the loud but want to cut the drone out , which would you recommend? To keep the sound but get rid of the drone
Installed the magnaflow on my 2022 V6 Camry. Love the sound.
Flowmaster Flow FX is built just like that Magnaflow!
Might sound dumb but I wonder what a combined exhaust would sound like. I have a 91 F150 with a 4.9L straight 6. Y pipe into a single 3" straight through cat, I'm thinking a flowmaster super 10 followed by a magnaflow 5" round body 14" muffler.
I have 2019 Twin Turbo F150 my question is have you done a exhaust upgrade on one yet?
Good video. I totally agree.
If you care about power stay away from chambered mufflers. Had to chop plenty of flowmasters on the dyno. On a stock silverado with cold air and decat it went from 287whp to 303whp by just cutting the 40 series off and made more power across the board.
So you straight piped it?
@@standhd Just for the dyno session. He bought a straight through muffler afterwards.
@@Silvermoss-Auto How much HP
with the muffler?
@@standhd the number didn't change when he brought it back. It's a straight through muffler without any bends so it didn't change the flow from staight tubing.
Magnaflow may give more hp! That Flowmaster has baffles which restricts and cuts ur power down... Sounds meaner but actually may slow u down a tad. For speed, long tube headers and offset or straight through muffler... Doesnt matter the brand really.
flowmaster make straight through...outlaw race muffler
Magnaflow DOES make more power, proven on dynos, especially on forced-induction vehicles. Performance Deisel mufflers are always straight-through designs like Magnaflow, Borla, etc. Magnaflow is basically a Borla with slightly less noise and more budget-conscious. Performance sportbike exhausts all use the same design too. Straight through design, essentially makes them resonators instead of mufflers, they don't restrict flow at all. They actually help scavenge the exhaust better than if there was no muffler on the vehicle.
I have Flowmasters on my 69 442 Conv. Sounds awesome.
which muffler do you recommend for a 1996 lexus LS400 that sounds better than the stock one but is still street legal?, thanks
I had a FlowMaster on my old Ranger that had a 4.0L V6.
Im saving up for a FlowMaster FlowFX dual exhaust for my 23 Tacoma TRD Off Road with the 3.5L V6.
just came across the video, very nice. Can I ask for your opinion through here? I have a 4th Gen Ram 1500 5.7 with at the moment a american thunder (should be a Flowmaster Super 40). I would like something more aggressive and I am torn between the outlaw and the Carven competitor or Carven progressive. How do they compare in sound (I watch all the videos I could find but they are a bit over the place - so I thought I ask you guys), thanks
Could I get some recommendations for my '02 Dodge stratus? I know its not a truck but I want her to sound like a dream and I have no clue where to start...
I've run nothing but Flowmaster on all the vehicles I've owned. I love the sound of them, I had a super 40 on my 96 F-150 302. It sounded like a 5.0 foxbody. On 04 Dodge Ram 1500, with the Hemi it came with a Magnaflow muffler. It didn't last long. It got a super 40, then a 44, but I wanted more aggressive. So, a Super 10 was the answer. It sounded amazing, like a truck should sound. I like this muffler so much that when it was time to buy another truck, the Super 10 found a new home on my 20 Ram 1500 with the Hemi. Sounds like a muscle car.
If you please , Which series of flowmaster fit for 2017 suburban ltz 5.3L V8.. Mild sound , is it 40 series?
When did Magnaflow switch to fiberglass fill? I've always known they use rockwool packing as it lasts 5x longer than fiberglass.
Probably because it was 5x the price of fiberglass? 🤔🤷🏾♂️
What do you guys think? 94 z28 LT1 i have an 80 series flowmaster with the stock tips it sounds great and loud, i just purchase a magnaflow muffler with stainless steel 3" tips , sould i change the flowmaster out or just swap the tips? Thank you .
Would this be good for a 4.0L OHV V6 Ford engine?
I love to see j, the dude who actually worked on my first chevy cobalt ls exhaust. Keep it up brother
Bro that’s awesome!! Thanks for your support 💪💪
@StraightPipedByGexhaust question. Would you recommend putting slp loudmouth mufflers on a 4.0 mustang 2010
It’s a solid system, but not our favorite. The Borla sounds much better. Available at Gexhaust.com or pull up in Oakland or davie bro 💪💪
I am planning to put a better sounding muffler on my mustang I got flowmasters on but they are too quiet. I gotta make a trip down to the Broward area to get it done.
@@GhunterGamingz pull up man whenever
I have a 2021 Chevy Silverado V6 Duramax Diesel,,, what do you recommend?
Hi. I have a 2023 Tacoma 4x4 Sport V-6, automatic..Can you provide me with a part number for the Flowmaster?
who makes a muffler video and doesn't post the two sounds?
Thank you for straight explaint
Yup, I can confirm this mans words. Have FM on my Camaro and MF on my Tacoma, they both get compliments. People think my Tacoma is a Subaru pulling up lol
Ford F150, 5.4 triton. i want Single exhaust, so Flowmaster Super 44 or Magnaflow?
I think the description is of the difference between a chambered muffler vs a flow thru design as now both companies sell both styles.
I've used both brands on many different vehicles (mostly GM V8s). I'm team Magnaflow! My #1 reason for 'performance' mufflers/exhaust is PERFORMANCE (not sound)- minimal restriction, maximum horsies, potential MPG. Magnaflow is straight-through and dynos prove their superior performance over baffled type like Flowmaster, Flowpro, etc.- especially in forced-induction engines where maximum flow is vital. My #2 reason for performance muffler is sound quality. Magnaflow (and similar designs such as Borla and ALL sportbike performance exhausts) delivers a smooth, deep tone resembling a more expensive machine (more refined, deeper, usually quieter) without the hollowed out banging on a metal trash can sound that a hollow, baffled Flowmaster (or FM copycat) usually offers. There are exceptions, both brands offer multiple products (I had a quiet and refined Flowmaster 70series on a Limousine in service), and I've had rowdy (typically smaller) Magnaflows, but the opposite is usually true. I currently have a GMC Envoy XL with a 5.3 V8 (LS-327 BABY!) with several performance goodies including cat-ectomy. Without the kitties to smoothen and quiet the sound (and popping) it is imperative I have a smooth refined sound like Magnaflow! But "Mo powaa babeh" is the main reason.
5.3 aka 325ci shares no engine parts with 327
No one said they share parts and no not many engines are the cubic inches that they are called so we old school chevy guys consider the 5.3 basically a reborn 327@@shawncordeiroTerraceBC
I hear what you are saying about more power but what good is it if the exhaust sounds like a$$? Magnaflows do sound good as do magnaflows but sorry Borla’s sound awful
i have a 2010 v6 highlander also my daily flowmaster super 50 or magnaflow? its also the family car but need low interior noise
Will a magna flow work on a hundai elantra 2019 and I don’t want it too be super loud just like a deep growl kinda thing
This man is lit 🔥
Flowmaster and Magnaflow are always the two I choose for exhaust
I just returned my flow masters because they’re made in China and still charging USA made prices. There are too many other companies making the exact same muffler for $30. Holly flowmonster is an example
@@Dodgechallengersixpack me too i did the same after i saw they are made in china i order the magnaflow dual rear exhaust for my tundra
I was a Flowmaster fan until I discovered Magnaflow! Pay a little more for a LOT more performance potential, much better quality sound, and not made by communist child slave laborers! That last one sealed it for me.
now this is a video straight to the point no gimmicks, if only that background music would have been lower
My bad
I so agree been using Flowmaster for 20 plus years had 1 V8 with Magnaflow so disappointed ☹️
Flowmasters sound like rocks rattling inside a coffee can.
I have a 1996 Nissan Pathfinder so Magnaflow or Flowmaster?
I thought Magnaflows had stainless steel and rockwool filler not fiberglass?
They do. He did not do any research what so ever before making this video. 🤣
So does the flow fx Flowmaster compare more to the 18-22 magnaflow since it is also straight through?
Somewhat comparable yes but I'd recommend talking with a local professional shop before making your purchase
I have 5.4 wimple supercharged F150 harly..and the cat back magnaflow kit sound so deep...i fully recomended!!!
If you like the old school and the crispy crazy sound go flowmaster...if you like an elegant deep sound go magnaflow....it's simple
Justin, great video. Thank you.
What Magnaflow would you recommend for my 2020 Challenger V6? Only want to change out the 2 rear resonnators.
Do not want any drone.
Thank you.........
Get Vibrant Resonators/
Magnaflow Muffler/ True Dual Xpipe
Flowmaster Flow FX Straight Through Muffler.
It would be a better video if the background music was not so loud, I could barely hear him
I have a 2017 F-150, 5.0 V8... I want a nice, deep, noticeable sound outside, but minimal drone in the cab. I don't want it to be obnoxious, but I definitely want it to be noticeable with my foot in it. Which exact muffler do I want? And keep the resonator, delete it? I just can't decide.
Magnaflow, in my humble opinion.
Go Magnaflow
Straight forward...love your attitude in sound review. I was torn between manga flow or flow master for my 5.3.. but flow master it is ..for the love of god!
Lol. Good choice bro!
So if I want to get the more aggressive sound on my 66 inline 6 with headers the flowmaster would be the way to go?
I would.. but always do massive amounts of research to hear the exact sound you want
What magnaflow size do you recommend on 12 model sierra 5.3l? 11 inch magnaflow?
For the 5.3L the 11 inch body Magnaflow will be aggressive.. they offer an 11 inch a 14 inch and a 18 inch . It just depends how aggressive you want the truck to be all 3 with perform great!! Check our website to order one up!!!
Hey guys, great video. Question: I have a 2005 Pathfinder that I have had for 16 years, it is in great shape and I've done some work on it to make it stand out. I am getting my entire exhaust system redone and was looking to get a muffler that is a little bit meatier than the original, something that is not going to turn heads or be too loud with the windows open. I'm thinking a Magnaflow but not sure which one to look at. Any suggestions?
Look up the magnaflow 10415
I had Flowmaster American Thunder in my 98 Ram 1500 with the 5.2. It rumbled. Flowmaster didn't make a cat for it, that was where Magnaflow came in. To top it off, Holley branded ceramic headers.
which muffler you recommend for honda civic?
I have that magnaflow muffler on this ⬅️ along with the high flow cat. 2inch all the way back. Little 1.6l deep, punchy and buzzy!
Love those magnaflows fiero
The video I needed. I have an 08 Silverado 5.3 with a flowmaster super 10 and I want something a touch louder. Any suggestions?
Carven R
Probably just a straight pipe???
Maybe removing the muffler all together
I like the flow pro max..nice muffler
How do you keep a deeper exhaust sound even while accelerating wide open throttle? Seems like they get all get chattery like slapping two boards together or something at wot
Long exhaust runs after your cats will cause that lame clap sound if you don't have a muffler inline somewhere but a straight through design muffler can cause that clap 👏 sound a chambered muffler placed as short as possible behind cat and
Chamber's mufflers with bigger bodies of metals have more surface area to distribute sound waves and short dumps behind muffler pointed towards the ground also project the Soundwave 360 degrees around any vehicle
I prefer the Flowmaster super 40 or super 44 chambered design
What if I put a flow master on my dodge dart what u think would it be louder then it was
It would but it won’t sound like a v8 charger
Any opinion on Gibson CFT OR SFT ?
Hows the highway drone on the two?
hi justin a questins ....what is your opinion about flowmaster super 10 versus chery bomb extreme...which would be louder
Cherry bomb would be louder most likely
@@StraightPipedByGexhaust thank
In my opinion, old school motors prior - early 2000 deserves the flowmaster. After that, the type of muffler you choose depends on what your looking for. Anything later than 2000 it could be flowmaster, magnaflow, corsa, borla...
What about the 6.8L V10? It is very hard to make that exhaust sound good. I currently have a Banks Monster exhaust on it but there is some drone around 1500-1800 rpms. It's is nice and quiet at highway speeds, though.
It is hard to make them sound good..
@@StraightPipedByGexhaust I need you to really try, though. We’re all counting on you!
🤣… I got youuuuu
can the flowmaster put on mazda 3 2.0 na ?
For a Dodge Challenger V6 which would you suggest Magnaflow or Flowmaster? @straight pipe
If you want to try and mimic the v8 challenger then yes Flowmaster . But Magnaflow would provide a cleaner sound
Get the V8
Get a new charger that’s a female charger 😂😂😂
Don’t bother. Sound is just WRONG
Flowmaster Flow FX Straight Through Muffler. 💪
I have a magnaflow on a 5.7 v8 the 350 motor and that aggressive as heck Idk what you talking about it all depends on your set up
Doesn't putting a flowmaster affect the warranty?
It shouldn't... Usually anything that is done from the catback doesn't void the warranty, but always check with your warranty provider before doing a system
Might put flowmasters(model tbd) on my vr6 passat. I think it would sound nice but of course no way of knowing when nobody else has done it afaik.
Exactly
Will the flow matter sound good with a 4 cylinder?
Go with a vibrant muffler.. depending on your car
I just had a magna flow installed on my grand cherokee with the 5.7hemi. question I have is do all Magna flow mufflers have the MF label built on them? I dont think mine does. Ive looked all over the muffler but it doesnt say magna flow anywhere. The body and everything looks just like the one on this video but without the MF displayed on it. It sounds amazing but I have to wonder if I got ripped off or do some magnaflows not say anything on them? It has the same welds around it as magna flows do. So I don't know what to think. Any answers would be great.
mine has the MF
Mine says Magnaflow on the body.
Have you found any answers about that? Is it a real magnaflow or not? Where did you buy yours from?
If you want to sound like you gained power from a muffler go with flowmaster. If you want to maybe gain a few horses go with magnaflow. Either way exhaust doesn't really add much besides noise, and you lose way more with baffles over straight through.
I've actually had several Chevy trucks with both flowmasters and magnaflows on them. I prefer the magnaflow
Dual flowmaster on my old school. Spintek on the 5 3 Silverado.
I have a 2008 F150 Harley Davidson.. The shop put a smaller magnaflow exhaust on my truck because they said it would give it a deeper growl. Did I waist my money 😢
No brother magnaflow is a great setup to have and if your not satisfied check with the shop I’m sure they can work with you
@@StraightPipedByGexhaust Thank you! I’m subscribing!!
Magnaflow = Sophisticated Deep V8 Sound
Flowmaster = Loud Old School Muscle Car Sound
I installed a flowmaster on my 08 sierra 5.3 sounded like a hair dryer when i floored it now i have a straight piped with magnaflow straight throught my 5.3 sounds perfect to me now
How do you have straight pipes and a muffler?
@@travisnapier2693 no catalyc converters with straight through muffler = straight pipe
@@rubenwong9574 if you have a muffler you aren’t straight piped. Straight pipe is just that, straight up just pipes after the headers. You could call your set up test piped.
I got a Mazda b-series/ranger V6 from what I'm seeing a 2.5 pipe is plenty big enough. the Flowmaster is quieter than the Magnaflow but the magnaflow produces more torque and HP.
What the best exhaust to increase mpg?
It won’t happen.. you wanna hear the exhaust usually, so you punch it harder
Just depends on the overall set up for me.
I prefer the sound of Flowmasters but have heard that the Chambered design disrupts flow and can actually reduce power compared to the straight through design of say Magnaflows...is there any truth to this?
It's been a rumor for awhile but there's no data to confirm it
"Theoretically."
Aha someone else pointed it out too. For power, brand doesnt matter... the least restriction the more hps! If u are going to change the muffler, that os what I would care about. Not the sound. U may even get a little bump in mpgs w offset, straight through, anything without baffles
The data is there, multiple unbiased RUclips videos of dyno pulls show that magnaflow consistently makes more power at midrange, even more at top end (where exhaust flow is most vital). One particular run showed tiny bit more low-end torque on Flowmaster, but only under 2000rpms. That could account for that particular vehicle not being tuned for the extra flow of Magnaflow (slightly lean). The whole point of 'performance' muffler is increased flow, and magnaflow has no restriction, that should tell you before you see the dyno proof! Flowmaster (with baffles) are not recommended for diesel or other forced-induction applications (even by Flowmaster), as they are deemed too restrictive. Flowmaster then came up with a 'straight-through' version, like Magnaflow, Borla, Sportbike performance exhaust, even glasspacks like Cherrybombs, etc., so they can compete in diesel/forced induction arena.
Choke Master
I ran flowmaster 40s for 20 years and switched to magnaflows because the flowmaster drone gets old after a while, especially since both my Chevys are catless with true duals. After the magnaflows break in, they will get a little louder and sound pretty good without the drone. I tow alot and the old school flowmaster 40s give me a headache after towing for a few hours, BUT...if you still have cats, the drone from the flowmasters won't be that bad.
I'm getting the magnaflow 14158 for my accord.
quick and easy vid. perfect. I wanna be friends with this guy haha.
Flowmaster is tin can 65 mustang with no compression. Magnaflow is deep rumble
My magnaflow on my 1994 Chevy 5.7L tbi is aggressive and loud flowmasters are weak
looking at magnaflows, I don't want db, I just want a little more rumble. so many vids on here are of really modified vehicles that are aiming for loudness. I'd like to know what these sound like on a stock LT1/ 1995 Buick Roadmaster Estate but it's difficult to find any examples. hopefully keeping the resonators on will help prevent drone at speed and they don't get too loud over time
Yea.. that’s a hard one bro.. I always suggest finding the sound before dropping cash
I've owned multiple LT1 cars, including the beloved Roadmonster! Yes, you DO want Magnaflows! (it's a dual exhaust, so you'll need 2) If you keep the cats and resonators on, it'll be very smooth and refined with 'proper' V8 depth, but quiet. The longer the magnaflow, the quieter it is, but these cars tend to be quiet by design, so keep that in mind. Magnaflows and resonators basically work the same way, so having 4 will give you quietness (canceling out higher frequencies and raspiness) without impeding exhaust flow much. I'm getting the Magnaflow on my Envoy XL with the 5.3 LS V8 tomorrow, there are no cats or resonators to muffle sound, so mine should be a bit rowdy at full-boogie. It'll be smooth, deep, and refined when driven conservatively, as it's Magnaflow afterall.
@@jeladsnikpoh1289 I did get magnaflows and they're very subdued but have a rumble at acceleration which is exactly what I wanted!
I did weeks of research for flowmasters but they were too wide and magna flow is bit smaller and definitely definitively more muffled easier to live with on daily or even weekends and no drone
89 5.0 LX; Which one?
