Took the plunge last week and ordered the Startech Exhaust. I've given up on thinking of trading so now I'll just get the potential out of one of the best looking cars on the road. The exhaust is not cheap, but after upsoluting and k&n's this was the next obvious step.

Had it fitted today (see gallery).
Startech quote 10bhp and you can certainly feel the difference, I would say their quote is very conservative. The note is deeper but not big bore stupid.

I used to have a small amount of pinking if accelerating from low revs and the car needed to drop a gear but now it just goes and so much smoother, even the gear changes, it really has taken out the restrictions the standard cats put on the car.
