This was a good one, I’ve seen so many muffler comparison videos and this one is my favorite simple and quick to the point!

[@dustinmccain1215]

Like the sound of the Hushpower muffler!

[@heckeng1234]

The problem with this test is that the exhaust is vibrating on the jack stands--the mufflers all sound good until you rev it up. If they were isolated better, you would hear the muffler sound instead of the rattling coffee can sound.

[@yamahaguy1732]

I like the super 10s they have more of a hotrod sound as opposed to high pitch

[@scoomagee]

the super 10 and Hp2 shortie have my votes!

[@s2000julius]

I had the Shortie on my bimmer. Man i used to shut off the radiio and roll the windows down every chance i got...just to hear that sweet sweet sound.

[@jasonneal]

I like this vid because it is a mock up of a real exhaust set up and you can hear all the different series. Thanks this helps

[@tommyChevelle]

Videos dont do any justice for any muffler

[@Rjellycrf]

i love the open header sound

[@MelonNuts69]

That car has some wide ass tires

[@ChooseLanes]

years ago I had a 93 civic with sohc vtec engine all stock and just for fun I did a straight pipe mod to it no cat and no resonator just piping straight from the header back with flex pipe of course straight up piping right to a 40 series delta flow sounded amazing very raspy had lots of snap crackle n pop sounds I liked it.

[@dskiller666]

that flywheel is hypnotizing

[@adidas1984x]

The 40s always were my favorite

[@KJOSS208]

I currently have a Super 44 on my 01 Ram with the 318. It's loud but not loud enough and as raspy. I'm installing a Super 10 next weekend. Can't wait.

[@69camarodrvr]

I'm actually friends with some of the Flowmaster guys who do these particular videos and the reason this motor didn't get reved up higher is that the motor is brand new and it belonged to a customer. I wish everyone could hear all these mufflers in person, they sounded freakin awesome!!

[@army1ty]

AWESOME MOTOR ! I liked the flowmaster delta flow 40s and the hp 2 shorties . You are definantly someone that knows how to build a good small block chevy not just someone that crunches together some numbers and throws a build together in their backyard ! Thanks for posting this vid , it will help me decide what type of exhaust I want to run on my 355 vortec s10

[@mikechilds9527]

Thank you for this video. Helped make my choice.

[@thetroll3899]

was guna go super 44 on h pipe on 351w but now guna get 10s thanks for video !!!!

[@wesh8337]

Bet your neighbor's just love you! LOL

[@KJBPSkipper]

THANK YOU!!!! I have been sayin this for years!

[@edcalzolari]

flowmaster the best exhaust company!

[@khaled0131]

Super 10 amazing

[@ACTVRLADR]

Open headers!!

[@454RagingBullSS]

I had the 40 series and move into the super44's. I am now looking into the 10 series for my 2011 Silverado.

[@malcomboy]

This is what I am getting in my 07 Ford King Ranch..04 - 08 Ford F150 Truck Mandrel Bent Dual Exhaust w/ Flowmaster Muffler Super 44 muffler. And just bought a K&N cold air intake for my truck.

[@o90GTo]

Nice video, wish you would have also compared the Super 40 and the original 40 series mufflers as well though. I can't help but point out that having 3 different variations of 40 series, each with a slightly different sound, is kind of confusing. Flowmaster makes so many mufflers these days, having so many choices makes it hard to decide what to go with, but this video is definitely helpful.

[@bryanneil1184]

Super 10 series 🔥

[@tilligetbig]

nice videos man!

[@chazzlehoff]

Awesome delta 44s for sure

[@ghazitravels7616]

Two 40 Deltas Plz :) Thanks that was helpful

[@MexicanMalo]

44s Sounds nice thx

[@2cayer2]

bon video merci! good video tank!

[@brwilli6]

Nice comparison. Thanks for making the audio so you could actually hear it. Looks like 3" pipe for all? Also, do you guys have a similar shootout from INSIDE the vehicle? I'd love to hear the difference, especially in an old muscle car. Thanks.

[@Triphax]

I have flowmaster 40s on my GTO sounds great under 3000rpm above that it almost silences out you just hear the gases rushing

[@xxdriftking027xx]

dat 67 chevelle in the back looks pretty sick :D

[@brngrhd1]

@BeastGT87 also wit nothing on the flywheel like a torque converter or flywheel it revs up and down so fast it really does not sound like a normal car.

[@iperez4life]

50, 50 low, 40, 44, HP2 & HP2 Shorty lol can't make my mind up lol they sound bad ass!!

[@antoniolopezportillo1147]

Very Nice chevelle 67

[@garyreid9799]

Putting a 302 in my 1975 MGB roadster so size is a consideration. Any suggestion?

[@reeupshawty4615]

great vid

[@andrewdhunter15]

Awesome video. Answered a lot of questions

[@LosMt2]

open header did sound the best on that engine but I have 2 super 10s on my 350z that give it the perfect tone

[@larry956]

so would you recomed to run pipes and muffler tips or just dump down? I notice in the videos yall use pipes with tips?

[@LoganTheRedneck]

yep so can i... its all a matter of preference

[@RipJawn]

Honestly Open Header Sounds Best. hP2 2nd best

[@noone42069]

YES! I love a good small block chev.

[@65elcamino283]

get the super 44's. they have a deeper tone than the super 40's. I have a 283 with super 44's that sounds meaner than most 350's and 383's. But, you have to be ready to live with the bass rumble in the cab. The ear banging resonance that reverberates in your chest and ear-drums with the super-44's is intense. I love it though. Its a hot-rod, right? Balls out!!

[@js73duster]

Still like the delta series muffliers.Both the 40 and 50 are on my cars.

[@MAPRTX]

Good job....I think I would of liked it rev d up a little more

[@ThirdEyeProductions1]

Hey flowmaster, what's the closest muffler that's similar to open headers? Would a hushpower or super 10 be the closest to resemble that open header type of sound?

[@ray29291982]

out all of those Mufflers I think S 44 sounds the best

[@tanman246811]

I have a 98 Mustang GT with a BBK H-pipe, magnaflow high flow converters with the super 40 series and its just not loud enough for me. Im changing to super 10 series this friday and im hoping it gives it that scream im looking for :p.

[@PMACll]

those HP2s sound nasty!! however, i would like to hear all of the mufflers w/an H pipe set up. x pipe gives the muffler a higher pitch. GREAT job though flowmaster! very entertaining & helpfull. HP2s who knew??

[@jasonneal]

If your gonna run Flowmaster's or any Chambered style mufflers, i would not recommend running a X pipe unless you want that raspy sound, H pipe is the way to go if your looking for that throaty muscle car sound

[@briandcarey3110]

Hushpower shorties

[@EyebrowsMahoney]

The shorties sounded the best for this motor IMO

[@ESPViper5001]

@DPense Because it's a drag engine. Big difference between something for the street and something for the strip. An engine with such power would benefit from no back pressure. The faster you get the air out of an engine with forced induction, the better. Why do you think there are guidelines for exhaust piping? You should only go above 3" if you're putting out 300-350+ hp and so on. There's a reason. Either way, do what you want, but it's not good for a street engine to be running open headers.

[@tomastilrem]

It will me 2x 10 series for me:)

[@bgascho98]

What cam is it from comp? Cause i have the 12-206-2 comp cam and love it.

[@Bronywithguns870]

Ive been looking for a new set of muffler for my 70 Chevelle. Its got a small block 350 so its about the same as the engine shown in the video but with out the comp cam. I actually had the very first model kind of Flowmaster. 42551 was the serial number and the original 40 is that muffler but with a 2 at the end instead of a 1. That muffler sounded good but I want something with a bit more bite to it. Something like the Super 10 or Super 44. Just want it to be loud like a muscle car should be.

[@Bronywithguns870]

I got the Super 10s and I'm not going back lol

[@bumblebestia]

Super 10 series !

[@jasonneal]

i think the H pipe sounds better then the X, expecialy on the deceleration, you don't get that raspy sound

[@DPense]

open headers sounds the best

[@P71ScrewHead]

well amigo, the Super 10 Series will be your Best option if its sound your looking for, in my opinion.. Another reason why i'd prefer the 10 Series is cuz it's way more Lighter/Less Heavier than the 44s, & when it comes to racing, every pound (lbs) counts, in my opinion.. ;) my 95 Town Car has True Dual Exhaust, ima replace it with TWO 5-ft long x 2.5" Stainless Steel Exhaust Pipe..lol True meaning of "straight pipe".. :) ;) :D

[@P71ScrewHead]

im replacing my stock dual exhaust with TWO 5' long x 2.50" diameter exhaust pipes.. i plan on leaving it like that, without any mufflers, X-pipes, H-pipes, or resignators, I think my car will make More Power that way, Can i get any opinions on what im going to do plz, if you agree or not?? Thanxxx.. :)

[@Foxstang4life]

Thanks for the vid it was very helpful but yet hard to choose , just wondering do the 50 series sound descent enough for an everyday driver or are they to quiet you think ? I do have neighbors unfortunately. Thanks

[@fenderplayer489]

@ESPViper5001 Question and I'm not being a smartass here I'm being serious because I was thinking of running 3 inch pipes all the way, how is that not good for a street car pushing less than 350 hp? I have a stock 95 mustang gt, well somewhat stock it's only making 275 at the wheels for now, would it be bad to run 3 inch pipes all the way?

[@LittleDragon77]

No, it's because it's a short duration camshaft, the RPM drops quickly and it has nothing to do with how quick the throttle linkage is released.

[@chevyboy1993aj]

What type of flowmaster do u think i should put on my 05 cadillac escalade 6.0??

[@W333dm4n]

do your mufflers have some kind of marking on them? I have flowmaster on my car but I wanna see which one it is

[@FlowmasterInc]

+SLAVCHEG They do. If you have a single outlet muffler, the part number will be located on the outlet side of the muffler case. If you have a dual out muffler, the part number can be found on the inlet side of the case. Once you locate the part number, visit,www.flowmastermufflers.com and enter it into the search bar on the upper left-hand side of our homepage to see what series of Flowmaster muffler you have. If you have any additional questions or are having trouble locating your muffler's part number, give us a call at 707-544-4761 and we will help you figure things out.

[@theotherguy22819]

Can you run the 10 series in the street?

[@stevedail5948]

Need to let it idle longer

[@LoganTheRedneck]

super 10's are the best sounding by far should have got them instead of my dnomax bullets

[@dannyho69]

Ey so wats better dual flow master or a cherry bomb glass pack I want to install dem on a 1970 impala it has a 350 engine

[@DemiGod00023]

They all sound good idling. But I personally dont like the reving sound. But its still nice.

[@SpeedyChevy72]

yall should try it with a stock 350,& which 1 is the loudest?,aneybody

[@steveflewelling67]

Idk ,mann that hushpower shortie has a nice tone ,

[@immort_Draconis]

WERE DID YOU GET THE VALVE COVERS

[@JohnnyAnderson1]

10 series sounds best! now lets hear that bad ass chevy 2 in the garage!!

[@daboys66]

What's a good dual muffler for a V6 3.8 I never heard a good deep sound on a V6 ? Thanks !!

[@FlowmasterInc]

Before we can give you the best recommendation we'll need to know more about the vehicle itself and the tone that you prefer. Please give us a call at 707-544-4761 and our Support Team will gladly help. - Jason @ Flowmaster

[@Michaelburton_33]

Is the hush power hp2 the same thing as a dbx?

[@craigshelswell8844]

hey guys you dont have to run glass pacs as well on these units to tone things down or what

[@diesel3519]

open headers

[@Gunshotglory]

open hedders sounded the best

[@bryan9450]

Matanga dijo la changa me parece muy buen very nice

[@tilligetbig]

bryan chavez jajaja

[@Dustin_JD]

Open headers all the way!

[@michaeldfv]

HP2 Shortie sounds the best.

[@gtoddwilliams]

This is a helpful video but as one guy said, videos never do mufflers justice. If you do this again use a free decibel reader on your smart-phone. Decibels are logarithmic so 80 is TWICE as loud as 70. And 90 is TWICE as loud as 80. Those 44s start to hurt the ears at close distance and can be annoying inside the car on longer road trips. Before you buy, try to hear them on a car with similar displacement. As they say, the 44s or louder will "wake the neighbor."

[@glbdsz01]

i can say the same stuff about every chevy engine and this one as well

[@ish_slowfx35gpt34]

I wanted to hear the 80 series

[@97chevyblazeron31s]

LOL YOUR PROBABLY RIGHT!!

[@BUTTONYTHUNDER]

Hp2's would be good on a sleeper

[@stinkydogfilms]

I'm looking for stock type quiet mufflers, I want them to as quiet as possible even when I lay into it. 71 Torino GT 351 Cleveland factory 4v auto with 2.5 pipes any recommendations?

[@FlowmasterInc]

For the best muffler options take a look at the Flowmaster 70 Series or the 50 Series Big Block muffler. These are our "quietest" replacement mufflers that will offer a mild to stock type exhaust note, nothing overbearing. You may want to give us a call at 707-544-4761 and talk with our Support Team about all of your muffler options. - Jason @ Flowmaster

[@EsenbekAliev_]

is this me or huspower shortie sounds quieter than regular?

[@arielgurgel]

i think the vibration on the stands took away a bit of the sound

[@bongspit]

I want some 10's

[@OldsPowered69]

Which Comp XE camshaft is it?

[@05front]

to all who watch this 1. it depends on your speakers, if you have a sub or not. 2. the mufflers all have a "break in period"

[@1979biggreen]

actually he says it has a mild cam in it, you proud of yourself now

[@DPense]

@ESPViper5001 your opinion not mine and if you lose power why do drag cars run open headers

[@MrDjrecon]

i want that motor,
