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.

Super 44 installed in about 15 minutes. Looks great, Sounds outstanding. Brings out the lows sound, nice rumble at idle, and makes a V6 sound l8ke a V8. Also, noticeable improvement in wheel torque, smoothed out the peaks in the power band, with a net result of faster acceleration.
