If you need the sound, that's your best bet.

Otherwise, get your self some piggie pipes (modified downpipes with gutted cats) from my friend Mike at Vast Performance. A fullback exhaust system should get you around 10 horsepower stock and 30 hp if you are chipped. I suggest the Autospeed Tru-dual catback. Dual exhaust systems have been shown to give the largest gains in power.

Stasis makes the best suspension for the S4. If you are cheap get the street sports. If you're a ballar, get the Motorsports.

Get RS4 intercoolers or the DUH FMIC to lower your intake temps and pressure drop.

Mike at Vast can also get you ported intake manifolds, phenolic spacers, big turbos, fueling kits, etc.

Hit him up and tell him I sent ya.
