Greg bough a B8.5 A4 and like most of us wanted more power. With started off with the APR stage I tune and of course that wasn't enough. Downpipe helped but still Greg wanted more. We ended up with and AWE exhaust, AWE intercooler, APR intake, CTS Turbo catch can, RS5 Style carbon rear diffuser, RS4 grille and Eibach springs. We are waiting for some more go fast part coming from APR soon. Stay tuned!
