I just installed the flowmaster 40 series American thunder. Ome of the best decisions of my life. Terrific volume and amazing sound. Love it. Great job flowmaster!

[@ernestoesparza296]

@marko Ingram...you recommend the 40 series? I just purchased a '18 charger RT and can't decide which one to slap on it

[@davidrossman7925]

I really appreciate the video, but if you're true intention is to help everyday people choose a muffler based on sound shouldn't a stock engine be used? Most people aren't running strokers.

[@RYTHMICRIOT]

I'm a chevy guy, but if you're gonna do sound demos with Flowmaster mufflers, use a foxbody with the 5.0 One of the best exhaust notes I've ever heard.

[@LOUCABRASI]

My guy 👍

[@italysfinest100]

I agree

[@NoneofYourbusiness-s8f]

My 4.6 V8 might have something to say to that.

[@michaelsutherland3981]

I agree with David Rossman you should use a regular stock V8 and a regular stock six and regular stock four cylinders that would be the best way to do it

[@motorman111jld]

I had a 97 Z71 vortec 350 with a pair of super 10’s wow it was an eye opening sound! Very aggressive especially because I had 4” tips 18” long. Loved it but my favorite mufflers I had was a pair of 12” glass packs. Sawweet sound for me!

I used to like that. Someone in a parking lot was sitting like a lump in front of you, get them a blast, they jumped. Or in underground garages, alarms will go off.

[@bradgris8918]

Hey Flowmasters, please redo this video with sound decibel readings inside and outside the Challenger for all your mufflers in the video so a potential customer can compare the loudness between all the mufflers and not just a few. This will also allow a customer to determine whether any particular muffler may be louder or quieter compared to their existing muffler with their own loudness measurements. There is a sound level meter app available to do this. Thanks in advance.

[@birdy7233]

I have a tip for you, the muffler will be loud

[@VirginMusicVideos]

Hey Brad Gris, please redo this comment and think about how the inside and outside of the modded Challenger for all of their mufflers in the video wouldn't be comparable to your shitty 150hp saab and it won't help you decide.

[@lovethesmellofracefuelinth7374]

I've had FM on 3 of the 5 Wranglers that I owned, and are some of the best quality built products made. Although they are a little heavy for racing applications, and are better with trucks/Jeeps. Thats why I went with 3" SLP loudmouth catbacks on my Challenger, and flow super well. Shes a modern Challenger SRT8, so it's heavy and is why they are a better choice. Anyone that has one of these big beautiful beast, knows what I'm talking about and can use all the help we can get in that area

[@tnandproud1918]

Got the Flowmaster Super 10 dual exhaust on my '06 Dodge Ram 1500 and it sounds so mean and growls super loud

[@PawlDunken]

Got original 40s on my 06 charger I had purchased super 10s getting installed as we speak cant wait to hear it

[@danmyers9372]

You either like the Flowmaster sound or you don’t. Not much middle ground. Older hot rodders grew up with the sound of glass packs in the 60’s -70’s. Flowmasters sound too tiny to many of us older hot rodders. Those who grew up in the 80’s and later tend to prefer the Flowmaster sound as that is what every 5.0 Mustang and Camaro had.

[@Mrfurballs]

Super 10 hands down , i have it on a 5.4L , stock cats still on , sounds amazing but Ive heard flowmasters begin to rust out over a short few years 😬 , cherry bomb extreme muffler would be my next choice .

The extreme sounds so nice

[@CHUCKNORRIZSFOOT]

Pinky poo Butt I did it on my 4.6 triton myself for around 75 bucks I’m telling you right now do it!! I got guys at work hating on me cuz he spent 300 at a shop to put flow masters on his Chevy 350 and it’s not even half as loud as mine

Outlaw is just a super 10

Anyone know how It sounds on a 6th gen Camaro ?

[@jordanposvar3616]

No its not. Outlaw is basically a straight through muffler. The super 10 has 1 small chamber. The outlaw is louder than the super 10. I have it on my mustang.

[@AdmiralRustyShackleford]

No, it's different. It's closer to a resonator or Dynomax Bullet.

[@nickobando2178]

One of the best sounding exaust are the (89 - 94) 5.0 Mustang with an H-Pipe.

[@orbitaljellyfish808]

Cammed so there’s more exhaust duration/sound, long tube equal length headers, Dr Gas x-pipe, 40-series flows. Maybe heads and a supercharger for good measure ;) Only thing crazier I’ve heard was a cammed 5.0 equal length shorties into a Dr gas with dynomax mufflers on a ‘94 with the flared LX fox style tailpipes. It howled like a banshee. This vid painfully underserves the mufflers in it.

[@jimcole2648]

Great comparison. I have a 300s 2013 year with the hemi and added the super 40s. Great sound. Had to remove the resonators to get the best sound. The only complaint is interior noise around 2k rpm. Rest is music to my ears.

[@manuelsantellan8808]

I threw 2 Super 10s on my V8 Audi s5 with an X-Pipe. Beast!

thank you for that tutorial. I subscribed

[@elijahcormier5239]

My favorite is the pro series. It has a high pitched aggressive sound.

[@JohnnyRebKy]

The ORIGINAL 40 is more aggressive than the super 44 every time I’ve had them. I dunno why they list the 44 as more aggressive. The original 40 is the only one that isn’t a delta Flow and it growls all through the rpm range....aka drone. Super 44 has a lot less drone at cruise speed. The original 40 is louder in every way in my experience Super 10 sounds like a loud tin can

[@PawlDunken]

Yeah I agree I have 44s on my ride now! It's like stock level without the drone

[@srica7366]

Turbo magazine did a flow,hp, and DB test on Mufflers. Flowmaster was the loudest and poorest flowing.

[@badass6.0powerstroke10]

I Agree Flowmasters Actually Flow Horrible. When you look into the inlet of any Flowmaster, the Hot Exhaust pretty much Slams into a Wall. I personally like the Dynomax Ultra Flo Which all come in Stainless Steel. Hell i believe even the Basic Dynomax Super Turbo even Flows better than Flowmasters.

[@juiced71]

Do they have a pro series but very quiet ? Sleeper etc…

[@prepboymagic]

Kelly MacMillan I know exactly what you mean.. the cons of driving a v6.

[@Hshjshshjsj72727]

Oof

[@ralphcruz8484]

How does the different mufflers affect the horsepower

[@Alexie3333]

Not much I guess. It depends on what spec of engine/piping. No muffler or low restriction can lowers the velocity of the exhaust flow and so back-pressure -> scavenging (puls more fresh air/fuel in the engine). So If stock exhaust with modded engine / bigger displacement, a bigger exhaust can make more hp.

[@jasonconaway69]

Need to do this with Black Widow mufflers.
