Ok lets begin, can anyone tell me where i can get a sports cat from and how much they cost. Also can anyone tell me what sort of Bhp this will free up?

What brakes can people recommend for me, I don't want to spend a fortune but may be getting a new Turbo and Chip, So i will need some serious stopping power! What size discs can go on without changing the calipers?

Does anyone know anywhere i can get some audi wheels from cheapish?

Think thats it.

Thanks for your help in advance.

No point in the sports CAT unless you have a larger bore system really.

Even just the exhaust will free up a few BHP.
