B7 Audi S4

[undecidedryan]

How hard is it to install the Rear Passenger Bose speaker grill? I punched a hole in mine, don't think I damaged the speaker though. Also, for a stock S4 what should I do to get the most sound out of my exhaust and should I buy the Intake Manifold from JHM. Also, is there a place to buy headers etc. for it?

To get the most out of your exhaust, get the JHM tune. IM and headers are great but expensive. Also, you need to drop the motor a bit to install the headers. Not cheap.
