What are the main after market performance mods available for the B7 RS4?
ECU, CAI, exhaust (but why would you want to change that already perfect note!), (dare I say it) supercharger.....???
What performance gains are achieved by these? And are there any mods which are approved by Audi and do not void the new car warranty?
