When I was researching Exhausts I was looking into it, but was never able to find some good info on it. I did find one person saying it wasnt loud enough, but who knows what his taste was. I guess I Couldnt justify spending the money on it without hearing it. So I decided to go with the GT-R and am completly happy!
to be honest, i am not quite a sound guy, thats why i chose g6 in the first place. all i want is better flow and possible performance increase.
