supersprint is $$$$. My friends M coupe has it and its nice but not worth the dollars(IMO) unless you want a really high quality system thats real quiet. For an intake go to ECISBMW.com. They make great intakes for almost all bmw's for a a good price. For exhaust I'd look at Turnermotorsports.com. Turner has all kinds of exhaust systems and intakes for almost any bmw. You dont need a chip for any of it but a chip would only help you out. The Shark injector on Turner is a good mod(komodo has one)
