Awesome sound Not too loud dual tail pipe (2 x 2 1/2") Lifetime warranty

I've noticed odd smell lasting few days after installation

Great replacement for stock muffler. Nice deep sound but not too loud.I do get better gas mileage with this muffler and power seemed to increase also.

The sound and the power.

The super-turbo dynomax muffler is definetly a must! She has a low grumble and throaty sound which is exactly what i wanted. I definetly noticed a hp increase! She runs a lot smoother then before.

Offers good sound. Kinda made my six-popper sound like a stock 305 or 307. It's not very large, so it fit right in place of my catalytic converter! It's also not too loud, it is quieter than when I was running open cat after the old muff fell off. It's a great muffler for the price. I'll definately be getting 2 if I ever get around to putting a small block where GM should have.

Bad interior resonence at low RPM's. Also the diameter of the stock pipe and the muff's in/outlets weren't exactly the same.

I have a '78 Nova Custom that has it's original drivetrain, a 250CID L6 and a 3-speed auto. Recently the muffler rusted off the back and I needed a new one. I'm a do-it-your-self guy, so I hacked the pipe off before and after the cat and put my new $32 Dymomax muffler I ordered from Jeg's there.

sturdy construction, inexspensive, great sound

had a few sharp burrs that could have cut my hands.

very sturdy muffler for the money. sound is great on my 78' trans am. maybe a bit too loud for every day use. resonates inside the car at around 2000 rpm but i like that. idle sound is great. gets a bit loud in the mid range then seems to quiet down in upper range. you really get a lot of metal for your money. no need to consider other mufflers unless you want somthing quieter.

heard about a short life span! 2-4 yrs?

The car sounds great! I instantly noticed the gain in low end torque, though i have not experienced any high end loss with these mufflers.

excelent sound good prices excellent quality and fit have used the complete systems too

non really cept having a hard time getting the one i want right now :( its not your typical application though.....

the car has a blown inline 6 in it and i needed something to make it nice and streetable as well as perform. it has an awesome sound with the header i use. it is a 2.5 inch in/out the car needed to be an all around performer at the drags auto-x and open road racing and be nice and streetable (keep the police out of my hair too) the car is also a daily driver and i want to hear the stereo as well :P i need a new one and one for my new truck and i have used them on project cars.

Bought 2 for true 2 1/2 " exhaust systems(headers too) upgrade for my chevy. What a difference. It has an awesome idle sound, a pleasing rumble at low rpm, and a resonating growl when opened up at higher rpm.

Really, Really, Really, Really QUIET!

They are extremely quiet. I wanted a deep rumble and I got a low squeal. I dont like them at all. I think my perf. actually dropped with them.

I love the way my car starts up now, and the way it sound when I accelerate. I''m glad I purchase these instead of the flow''s.
