another thing you have to realize is that exhausts will sound totally different on 2, 3, and 4 valve cars. and for what its worth, i love the sound of my FRPP Stingers
x2. 2 of my good friends who have new edge GTs have Mac catbacks. One with an X pipe, one with a PRochamber. Both sound sick, but I love the sound of the Flows. ME, lol caring what anyone else thinks...though, everyone loves them.
