This is why Flowmaster offers over a dozen different series of mufflers, as well as several Cat-back and Axle-back kits, for nearly every popular make and model of vehicle. #Flowmaster provides everything that you need to tune the sound and performance of your vehicle's exhaust system to your specific wants, needs and budget. In this video, 8 of Flowmaster's most popular mufflers are tested, from mild to aggressive, in order to help you figure out which muffler is right for you. Keep in mind, the sounds heard in this video reflect how the vehicle sounds from the exterior and are not representative of the interior noise that may or may not be generated inside of the cab under normal driving conditions.

Here's a muffler test for you guys, we are going to use the most uncommon car. Makes a whole lot of sense

[@splash5974]

Anyone else still confused on which muffler they like? 🤔

[@ShortThrowShifting]

I think I like the pro series the most. It provides the bite and throat, but without causing half the neighborhood to hate your guts. I find it suits my taste the most, as it provides a clean sound, without an overbearing sense of power.

[@MiddleTNSirens]

In my family, We have a 1965 ford mustang with a 408 stroker, which has Flowmaster 44's, and I have never heard a car sound as good as it.

[@buschg7106]

Super 44 sounds excellent

[@axeldiaz9743]

I have the 40 series installed in my Chevy Silverado and sounds beast!! I love flow master.

[@devinrivas7016]

I'm running the supper ten on my 1973 camaro with long tube headers and puts out 600hp and it sounds great with the super 10

[@oceanwaves83]

Pro series all the way. Healthy bass is just a bonus. Performance is #1.

[@kagome122885]

They all sound good. They all have that deep tone that sounds like an off shore racing boat exhaust which I love!

[@Keego0201]

I was thinking about stepping up my challenger R/T to a 3" exhaust, but that Super 44 sounded really good. It's under consideration for sure.

[@gordongreninger6109]

Big 3" single. Flowmaster 2 into 1 merge, Flowmaster Pro straight thru muffler, with a Flowmaster Super 10 as a resonator. 88-95 GM TBI cars and trucks respond real well to delete Y pipe and period cat. Replace cat with modern hiflow or not. This mods good for + 10 to 20 whp at any rpm and +1 to 1.5mpg at the pump. Sounds great!

[@deathbringer0520]

This are the drive away vids to compare them directly. Hope it helps. 2:19 - Super 50 3:12 - Pro Series Hushpower 4:29 - 40 Series Delta Flow 4:44 - Super 40 4:49 - 40 Series 5:13 - Super 44 5:36 - Super 10

[@juanmontoya2814]

40 series on a lt1 z28 , YEEEHHH BUDDY!!

[@vmiley1]

I just put on a Flowmaster FlowFX axel back system on my 2018 Ford Mustang EcoBoost. I also have your Scavenger Series Resonator Delete Y-pipe. What an awesome, low toned sound! It's exactly what I was looking for.

[@kingdick6567]

I'm running the super 10's with mid muffler delete. Sounds like a beast. I do recommend cold air intake to really get all the exhaust notes and little more hp.

[@mytubebobbie06h]

I think I will go with the Flow Master Super10 for that very aggressive, muscle car, and very distinguishing and unmistakeable Mopar sound....

[@r1rider174]

I have a new 2015 Dodge Charger RT and installed the Delta Flow 40 series w resonator delete. Sounds awesome for a Father with 3 kids. Aggressive sound on startup, low idle and heavy gas, but very, very mellow when cruising at street or hwy speeds. No drone when cruising, highly recommend for someone that wants muscle sound, but no drone when cruising.

[@FlowmasterInc]

+Shawn J. Glad to hear you like it!

[@chicagotypewriter4534]

Thank you Jesus for this vid😂.....I'm so happy right now

[@furiouswolf777voodoo4]

Super 10 put a smile on my face...

[@edwhite101]

Very informative vid! I installed the Flowmaster 44's on a 2015 Chrysler 300s HEMI. The sound was amazing. But you are so correct, each engine will put out a different sound. Mine was not as loud as the 44's installed in this video.

[@jessepalmer3165]

Ed White but it still sounds amazing right because I am deciding if I want to purchase them because right now I have the outlaw but they are obnoxious with the drone levels

[@FlowmasterInc]

The Outlaw Race Muffler is our most aggressive replacement muffler, originally designed as a muffler for the track. You can try adding a resonator into the system to help lessen the drone. But, as aggressive as the Outlaw is you may want to consider going down a bit to the Super 44 or even the Super 40. You can always ring us at 707-544-4761 for more muffler recommendations. - Jason @ Flowmaster

[@edwhite101]

@@jessepalmer3165 Yes, it still sounded amazing. I've since sold the 300 but have plans to purchase the same car just newer model. I will be making the same exact mod on the new one. Thanks.

[@Des420]

The funny thing is, I run the 40 on my truck... Which is anywhere between 275 and 300 hp and it sounds almost identical to the 40 on this car.

[@octanne704]

After watching this a year ago I chose the 40 series for my 2001 Lincoln Continental sounds so beautiful btw did I mentioned it turned my car to a hotrod definitely made it a sleeper

[@CopperAboriginies]

Love the super 10 & super 44 sound lol. The 10 is my favorite.

[@WOLF10307]

I have Flowmasters on my 2014 challenger 40 series and its sounds way better than the stock that came with the car from the dealership!

[@MrNiggaplz1000]

Just put a 10 on my dodge ram! Sounds effin sexy!

[@themooseisloose100]

i drive a 1975 chevy luv with the original 1.8 motor. i have custom dual exhaust side pipes and it roars, let me tell ya. its fun when i drive to school but it absolutely sucks when i drive long distance. the noise will kill ya and you can't listen to the radio. in all honesty, i think everyone should keep the quiet stock exhaust but get whats called exhaust cutouts. that way you can be loud when you want and quiet when you want.

[@serenityinsilence]

I have the original 40 series on my 305 Chevy and its decently loud. I really like the way the hushpower shorty series sound on my friends 4.6 f150 with turn downs.

[@michaeldillon719]

Flowmaster is the best in the business as far as im concerned, I've had them on all three of my cars that ive had so far (jeep 4.0, ford 5.0, and vw 1.8t) they've all sounded awesome and never rusted. Unlike some competitors I've seen hehe.

[@FlowmasterInc]

+Michael Dillon Thanks for your support!

[@craigcolvin8882]

That's one beautiful challenger right there man. It sounds muscular and looks muscular as well. Richard Hammond would love to drive that 74 challenger especially one with a 550 HP 408 Stroker.

[@DarkpawTheWolf]

This was great to get an idea on the differences. I still can't make up my mind between the super 10 and the super 44. I want volume outside, but less drone inside at highway speeds, so it's probably looking like the super 44. But the sound of the 10, it's actually better than just straight pipe. So hard to choose.

[@kartune551]

the last one is what i want 😍😍

[@matthewlee8538]

I have a super 10 on my truck with a straight pipe and I'm not sure the tip. But it sounds great!

[@timothyfoeks6446]

I put two flowmaster super 10 series under my old 1999 dodge ram 1500 it was nice and loud I loved it !!!!!

[@allawialsabbar893]

Good job nice mufflers I like it 🚀👍

[@petehegger6320]

I run the super 44's on dual 3 and a half inch pipes on my BBC nova. The conversation with the neighbors is gonna have to wait..lol!!.

[@Alxm225]

Got the 40 delta flow and I am happy with the better sound on my dodge Durango , and I have seen a small rise in gas mileage :D

[@southerncountryboy8]

another option you have instead of buying stainless, is spray painting the muffler with ultra high heat flat black rustoleum. it seems to work pretty well.

[@dougsholly9323]

I was about to give you guys a hard time about babying that Challenger, but while I was typing I heard you finally let her loose at the end of the video :)

[@danrichards2727]

went crazy trying to figure out what to put on my 2014 mustang GT. had it for over a year with factory mufflers. got tired of it being too quiet. finally went with the super 44. has a lot of interior drone at 70 mph. i had to get used to turning my stereo up but im good now. a friend that i didnt tell i put flowmasters on it heard me leave when he was outside one day. when i came back he told me how good it sounded and he didnt realize the factory mufflers sounded like that lol. i told him i put the super 44's on it. he was impressed. told me dont change a thing. i have the factory duals on it and since he said that ill leave it dual and not put an H-pipe on it. save the money lol.

[@JOSEC760]

borla sounds good on them GTs. especially with an x pipe

[@jamisonlgolonka]

yes, you can install them on any vehicle. I heard a V8 Jaguar with them. It sounded nice too.

[@midnightrider5937]

I running a sub10 sounds really good on my dodge ram 1500

[@mikeanthonysarchives]

too many people bash flowmaster. I love the flowmaster sound. pure bad ass!

[@starbattles1]

Should have done this on a 300 hp mustang. Thats the classic flow master sound we all came to know. And see how the others sound on the same type of car. They always sound best on a stang.

[@Shortay1325]

I had the Super 10 w/ dual out the back on my V6 4.0L Ranger. Best sounding V6 I have ever heard was my truck, I miss that thing.

[@Ig2gpce]

Did you have to order the Super 10 online?

[@arch417powersports]

Mine sounded ricey on my 4.0L Nissan Pathfinder... So I put a Super 40 and sounded way better.

[@gabemendoza650]

I've got a 10 series turn down on my 69 camaro couldn't be happier

[@damiennewyorker8105]

Super 40 Delta Flow Wins! It has the best bass without sounding stupid! At one point, you want the engine to make the sound, not just the muffler.

[@bobisthebuilder3982]

One of the tricks I use to get decent sound with a stock engine especially with a four cylinder. And it’s not terribly expensive. Cat back upgrade. 1) Pipe. Increases 1/4 inch for every 2 inch diameter. This also allows for a higher flowing cat so you are still smog compliant. Push the muffler as far back as the frame ground clearance and mechanicals will allow just before or after the rear axle is preferred. . 2) Muffler upgrade. Same inlet and outlet size upgrade. Turbo mufflers work well shorten and skinny them down by 25% from stock. Makes for decent tone and reasonable expense. If the outlet is bigger than the outlet you should be good. 3) Adding a glass pack between the cat and muffler can adjust the sound as well. Upsizing the tail pipe helps. However it depends on the car so let your ears and wallet decide.

[@NissanTy]

The muffler was rusted out on my 04 chevy trailblazer with the 4.2 inline 6. So reading around a lot of people recommended the super 44 (some trailblazer and some with other brand vehicles). I got one and had it welded in with the stock can resonator in the back and it was not loud at all. So I cut the resonator off and put a piece of straight pipe in place and that fucker is loud! Not annoying loud but just louder than I wanted. A lot of people said this muffler was quiet. Now I wish I went 50 series. But the muffler sounds good on the big inline 6 and has a low tone to it for it not being a v8. I will definitely buy another flowmaster muffler.

[@shak541]

what kind of resonator was on your car? Was it a box style or like a straight through? I personally got a super 44 and its very quite. Think of the sound of a stock grand prix. Very quiet. I was gonna remove my resonator in a couple days.

[@NissanTy]

shak541 The Chevy Trailblazer has a huge mid section muffler and a little can style resonator at the back. My huge mid section muffler needed replaced to I had a super 44 put in place. With the resonator still on in the back it was a little quiet so I cut it off and welded in a piece of straight pipe and that made it excessively loud but I'll deal with it and I am growing more fond of the sound. Hope this helps with your grand prix.

[@shak541]

thanks. my car is the intrigue but sounds like a grand prix stock exhaust. I shall upload videos soon to see before and after myself too

[@Flash635]

I'd like to see dyno results for these mufflers.

[@Godzilla-du9ex]

This video help me alot was undecided but now I got it, Thank you I'm goin with Super 50 more like an original sound.

[@efd5803]

That Hushpower sounded the best to me! I am looking at buying a 2013 Charger and want to change the exhaust ASAP!

[@TBird100636]

Look for the model number laser etched on the inlet or outlet side, then look it up on flowmaster website.

[@gunshow589]

my personal favorite is the Super 10. really aggressive sound

[@olironlungs]

Am I the only one that wanted to see roasting tires....

[@ayozayTL]

GREAT PRODUCTS HERE! RECOMMEND THE SUPER 10!!!

[@tskwared667]

i wish they did a video like this for people who have an inline 6 or something

[@MarkMeadows90]

That Hushpower Pro Series muffler ain't that bad to be honest.

[@tskwared667]

im just saying that they should make a video showing the sound of each muffler on different types of motors rather than just a big block v8

[@todtandy8077]

I have a Vic straight piped. But it does have og 40 series dumped at the H-PIPE but I got a friend that had a xj jeep that has the super 10 welded to the down pipe. It's loud as balls🙃

[@72troy455]

I use the super 10s on my daily driver. 485hp sbc S-10 Blazer. Totally tolerable.

[@rakerbill60]

And if you noticed, he didn't stand on it that hard. It was a demo on sound, not how fast the engine can rev.

[@epiqa1177]

wow thats a nice sounding muffler

[@l9ikjam]

I have the super 40's on my challenger and have no trouble talking in the car while drive whether it's at a normal speed or fast. The video would have been better if you would have let the car sit in idle a little bit longer with the different mufflers installed. but flowmasters is the best on the market and they will be on every car I own.

[@mikexcanxjerk]

What year is your challenger ? And did you delete the resonators ? And how much did it cost to get and install ? And how loud is it from 1-10 ?

[@l9ikjam]

It's a 2012 and I purchased the whole catback instead of just the muffler. I paid $50 to have it put on. Loudness is about a 8. Now.

[@mikexcanxjerk]

l9ikjam see I get a little confused on that what is exactly is a "whole catback" ?

[@l9ikjam]

The catback replaces your whole entire exhaust. Some people replace the muffler with 1 of the flowmasters mufflers.

[@chainreaction2944]

Super 10 on my 5.3 Vortec all day. These are great mufflers.

[@christianjohnson5803]

[@heathcalvert8820]

Love the super 10 would like to hear it on a 5.9 Dodge Dakota

[@clintonmumbower4461]

I have been going back and forth on which muffler to get for a while. Either the Super 44 or the Original 40 both single in and dual out for my 2014 F-150. I have saw two different comparisons from flowmaster inc I believe that conflict. When running this on my 5.0 F-150, which is truly louder? I get louder isn’t always better but I just like being able to hear the rumble when started a ways away. I want to hear it rumble while it’s outside warming up haha.

[@LanndynCarnateBowling]

Just installed Flowmaster 40series on Monday into my 04 Monte Carlo ss supercharged. I love the sound.. If I want to make it even louder,what should I do? My muffler shop said it takes two weeks to break in n get louder! Thanks FlowMaster.
