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.

Muffler was quality in appearence and sounds just as I thought it would not to loud but a nice throaty growl, in fact now I wish id bought the whole package for a true dual exhaust system to give it real breathing ability, my muffler tech says it cant be done on my vehicle, im sure all I need is another cat converter xpipe muffler and tail pipe and it would work, may need to run tailpipes on passenger side because of spare tire blocking pipes(no room to pass between spare and leaf springs),usay?
