cat replacement pipes make the st170 sound tinny as hell, and may get you 3-4bhp if your lucky.

They are pretty well tuned anyway so the only way to get some decent power out of it would be forced induction with a turbo or supercharger, or you could even use nitrous

hi thanks 4 replying 2 my post, i was'nt really wanting to go 2 the expence of a turbo or supercharger the now, i looked into getting it remaped it only gives it 8 bhp forŁ200, or a power boost valve

power boost valves do nothing on a fuel injected car.

As I said in my original post, they are well tuned as standard, there's not really a lot you can do to them unless you are prepared to spend some good money on them.
