Flowmaster vs. Thrush Sound Comparison 

Thank you for watching! Subscribe if you want to see some more videos like this one!

At idle, the thrushes sound like a drum line of snare drummers!

Flowmasater 4:54 & Thrush 7:11 Both sounds great!

I always did enjoy the " sweet sound of my Thrush Turbo single exhaust " on my 1972 Monte Carlo , I miss it and the car to .

THRUSH muffs Sound much better! Adjust your idle set screws in until idle drops (It's about a minute delay) reaction then adjust them out a tad till it idles up. I use a tack & dwell meter. Not sure what size carb you have on there or what kind but you may need to rejet it with smaller jets to get your mixture right. I like edelbrock carbs for the street & reliability. The IROC hood would look better❗

The Thrush mufflers take me back to the the deep throaty 70’s sounds. Nice.

Thrush sounds good

Thrush most definitely, I put a dual out on our 90 Eldorado and it sounds amazing, liked better then flowmaster

Put a thrush on my 85 Tbird. Love it way better than flowmaster. Tried flowmaster and magnaflow on my dodge 2500 and the thrush sounds better than both. Running thrush's on all my trucks. And V8 cars.

Have thrush mufflers on my c10, sounded great, 7 years now and theyre a little rotten now. No ice or snow where i live. Going to get the same ones put back on anyways.

Thanks for the video, I couldn't find any other good comparisons on YT and I've been torn between the two for awhile now, This vid helped a LOT!

Show off your Comet, it looks good. I vote for the Thrush mufflers. I always hear people say “old school” when talking about The Flowmaster sound. They are more of a 90’s sound to me. I think a turbo muffler sounds real “old school.”

Nice Video! was considering getting the Thrush from summit so you helped out alot, one suggestion though- put turndowns on the tailpipe/end of mufflers, the exhaust is ruining your bumper paint! GJ again, and nice car !

Also those turbo mufflers have glass packing kinda like glasspacks that take a few hundred miles to break in they will sound different after a few hundred miles where as a chambered muffler like the flowmaster does not have any packing and won't change in sound

The Flowmasters sound too "tinny" for me. I've been searchin and searchin for a video of an actual muscle car with some "quiet" mufflers so thanks man. I got a straight piped 383 stroker and I love the sound. Been crusing around like that for about 10 years but recently I moved into an apartment building and all the neighbors are little bitches.

Thrush perforated mufflers have a more settled tone...suits the 3rd gen. Nice choice.

Thrush 👍

It's. Holleys sniper self adjusting system, no computer (just by it self) adjusts to atmospheric conditions great if you don't care for adjusting carberators. BUT Turbos for the win!!! much snappier sounding and you hear your Engines valves chambers popping and snapping way better and, using an a agressive camshaft (IE) one with more lift and tighter lobe seperation, will really sound more race car. Been using them back in the 80s love the Engine sound better than lame cherry bombs or flow munsters......

Very helpful considering a muffler change for more power don't want anything too loud

Flowmaster all day , every day and twice on Sundays!

The thrush turbo sounds perfect on my 98 s10😉

Rumbly sound with the Flowmasters, Thundery sound with the Thrush.

I've used those Thrush turbo mufflers on a small chev 350cu . Lol I put those mufflers on backwards,on purpose. OMG THE RUMBLE!! THE SOUND AS SO LOUD IT PISSED OFF THE POLICE IN Victoria B.C Canara

The thrust sounds like a top fuel dragster

The Thrush mufflers are much better. And as far as the hood? Lose the one that's on the car now and replace with the other one. Thanks for sharing! Oh and BTW, I'm really digging your Maverick!! Had one similar bad in the day, (in 1981) except mine was green. 😉👍👍👍

Those thrushes sound like a dragster.

I ran flow master for 20 years and thrush turbos for the last 8 or so.

True dual exhaust WITH an X pipe? Genius!

Flowmaster has that signature sound. Hard to beat it. Maybe Magna flow for a different sound but not a big fan of turbo mufflers or glass packs.

thrush sounded better at idle, but the flowmasters sound 100x better in the rpms

Thrush 100%

Man , I had an 85 silverado that was had everything done to the motor and you could literally hear it from a 500 feet away inside a brick building and unfortunately years ago I sold it and what makes me sick is today the motor work alone would cost more than I sold it for. Picture every mint jacked up silverado you see online with 12 inches of lift on it all together and see what the price tag is and unfortunately almost 20 years ago I sold it for 7500. Now I'm looking for another one and kicking myself in the ass for not just throwing it in the garage and letting it sit.

Sounds much better.. but try the walker super turbo better version of the thrush and better flowing just as quit just much deeper old school sound I have run both for many years

WOW GUY IS THAT A CYCLONE NEXT TO THE CAMARO I KNOW THAT BACK LIGHT FROM WHEN I WAS A KID I BELEIVE A MONTAGO ALSO HAD SAME BODY IN 1970

Put the flow masters back on ,and leave the 4inch hood on with black SS stripes. That way a muscle car guy will see you coming from a distance and that you mean business .

Should have went with thrush welded but those sound nice and rumbly

I have a set of Thrush welded"s on my 07' Monte Carlo SS but wouldn't mind shaking it up. Sounds decent.

I have a set of thrush dual chamber mufflers, more or less just like flow master, on my mustang fox body with off road H pipe and sounds exactly like my friends fox body with same specs, same sound for a lot cheaper, just here to see how the thrush turbo sounds coz I was wanting to put one in my zx2, I want some sound with out sounding like a fart cannon

Because you have your muffler at the end of the exhaust that needs a tailpipe, put the mufflers further up in the exhaust system or get the proper two into one and exhaust for that

Oh man, those Thrush mufflers sound so much better than the Flowmaster 40s. Did you get any droning inside with them?

Vote for Thrush and factory hood

Just paint the hood leave the thrush on they sound awesome nice job

Get some tail pipes/Tips bro. Sounds nice.

Most definitely Thrush mufflers, sounds much better than the FLowmaster.

Thrush baby .. flowmasters always drone.

As a musicians point of view, The acoustics on the 2nd instrument, sound profoundly better and is within my pitch preference.

You need to put on a nice pair of chrome exhaust tips to keep your bumper clean.

All you needed was some turn downs on the Flowmasters

I have Thrusher Turboes on my 2007 Crown Vic Interceptor

Would sound better mounted under the car instead of back by the bumper

Flow-master sounds way better man!👍🏻

The Thrush Welded are pretty good. They're a 40 series knockoff but the case is pretty thick so it doesn't sound quite as hollow, and in my experience doesn't drone bad at all. Magnaflow makes a 2 chamber called the Rumble and it's just as good as the Thrush, if not better. Also, another favorite of mine is the Hooker Aerochamber. It's kind of a Flowmaster and Magnaflow mix, sounds awesome, flows as well as anything and no drone.

Love the video bro!!!!!!!!

Ooh yeah brother that's sounds 👍 awesome

If your going for the sleeper look try the original hood,but if you might put the turbos back on the cowl hood. Also how's that sniper efi working for you, I want to try it out but not sure yet

Damn bro hit the fkn gas

thursh for sure sounds better. i have duel thrush mufflers on my 95 roadmaster sadan *5.7L lt1* and it sounds awsome.

I do like those flowmasters.. iroc hood. :)

I think you should go for the borla atack exhaust they sound crazy badass

Thrush for sure!

I've got a set of 40 series on my 85 Corvette they sound great but drone me to death on the inside of the car can't hear my radio half the time and it gives me a headache I don't mind a loud good sounding car if all the noise would fracking stay on the outside of it so I'll replacing them soon just haven't decided on muffler's to get.

Wish you had test on your comet. I,m looking for something to put in my comet with 302.

He said he had a mild cam lol

and i notice it left black stuuf on your bumper maybe you should move the rear pipe back some . but it sound tuff throw .

Do a video on the Mercury Comet!

IROC hood for sure.

Thrush !!!!!!

would the thrush sound good on a gmc canyon? it’s got the 3.5 i5

Are you running like way rich or burning oil?

Nice Comet 👌

You wasted your time installing the thrush mufflers even if they were given to you FREE. The flowmasters were ok but you are really missing the point? buy yourself a set of series 10 flowmasters they are cheap stainless and 1 third the size and weight and 2 times as aggressive. save weight money and more flow ? whats not to like ? also you got a small block chevy cheap and easy to work on pop the heads off and machine the tops of the guides to accept teflon valve seals you can buy the cutter to do this on a hand drill cheap and you will never have smoke coming out the rear from valve seal issues ever again. for seals and cutter and headgasket and intake and exhaust you might be out $125 tops and now would be the time to upgrade the springs and or port the heads etc.

The most sane Ohio car enthusiast

Can the thrush be put on backwards and cause problems?

The flowmasters sounded the best.

ur a good guy

Flow master all the way.

I got some thrush mufflers on my firebird

Honestly the thrush doesn’t sound bad. The flowmaster just has a more throaty sound.

I like the thrush better

Hello what it's your cam in this video?? Thanks 👍

I can’t stand Flowmasters - they’re basically echo chambers. Thrush sounds so much better.

sounds like jiffy pop corn!

I'm more interested in the 70s comet to the right

Whats up with the Comet to the right in the video?

how is the 1800 rpm drone sound?

Hey I have a Chrysler 200 L I was looking to upgrade my exhaust system which is better to get the flow or the dual?

Will it sound good on a V6 single exhaust.

Hey how do you find out the offset that you need for the thrust mufflers

Thrush all the way!

Original 40 or super 40?

A little rich there buddy?

What about that Maverick!?!?!

Iroc hood and thrush

Cant believe it but I like thrush way better. Doesnt have that tin pinging sound flowmasters have.

IROC HOOD and Thrush.

Irock hood

Turbo mufflers of any brand suck. They neck down to 2" or less inside and they are loud and sometimes raspy. I made a dual exhaust for my built 350 sbc C4 corvette. Started with Turbo mufflers thinking they would be quiet enough. Wrong! Get Flowmaster FX! They are true to size all the way through, and they are straight through. And believe it or not they are way quieter and deeper sounding than turbo mufflers!

Just sayin

in my opinion the flowmasters sound all-natural & the thrush sounds homemade ?🤭

Not bad for a $25 muffler
