Not really going NINJA over all. Just want to keep the fact that I have a TT in CA a little bit less noticeable. About how much more power would I get out of having a pipe an extra .5 inchs? I mean I already am spending a lot on the TT and I already bought a new exhaust. I would hate to spend more on another exhaust for like may be 10 hp. Or are we talking like 40 or something? I was also wondering had anyone ever heard or seen the GTM dual quad exhaust?
