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.

I wanted something that would be deep and a little louder my silverado but not wake up my neighbors loud. If you are looking for something like my first sentence said this is it. There is a little drone in the cab but you can turn your volume on your stereo up just a bit and it drowns it out. It has the perfect deep tone I wanted and the exact amount of loud I want as well. Great product!!!
