hey guys I have an 01 cobra, ive been wanting to upgrade the exhaust for a while now but its so hard to decide what to get. my question is mainly on mid pipes, I heard the x pipes are raspy and don't really sound too well which do you guys prefer the sound of the O/R x or O/R h pipe also how much quitter is the H pipe compared to the X pipe and which brand are you running on your stang? thanks for the help
