the car's computer might go off if you do that.

maybe a free flowing cat (racing cat) or better exhaust system. Some custom exhausts like the ones you see on ricers may actually decrease your horse power. Its already got 225hp, for significant gains you'd actually have to plop down some serious cash. Plus, if you look on this forum, lots of people get around 15 hp from an intake and exhaust setup anyways. And those people are buying some really good stuff like Eismann, Dinan, UUC etc as well as Gruppe M intakes.

I guess you need to look into Turbos or Supercharger systems to get some serious power increases.
