Don't you all think they sound awesome?! I kinda liked
the stock sound but did not have the punch like the 360 or
F355. EURO4, I guess.......I did put in the cat-back exhaust system already and it became quieter than the stock
exhaust but with better sound. The sound above, have their original catalytic converter pipes plus the cat-back system. What I think I would do now, is to have the cat-pipe installed and achieve the above sound. What do you all
think? Too loud?, tacky sound? etc.....your honest comments are very much appreciated. The cat-back exhaust was 8000 bucks and the cat-pipes are another 2000 bucks. So It will be a total of 10000 bucks modification. Worth it? or not?

Thank you.
