Love the sound of my 40 series. I put it on my 99 Trans Am. Sounds great and turns heads. Love it.

These mufflers sound good outside of the car. They give the car a nice growl. I have a 1968 Firebird with a 400 engine. A little more resonance inside of the car than I expected. I am running 2 1/2" exhaust.
