Keeping It Classy

   

What happens when you combine luxury with performance, then add a pair of Borg Warner rs4 ko4 turbos,710 diverter valves, an ecu flash, and a 4 bar pressure regulator? You get about 300 whp out of this 2001 Audi S4. With custom 2 1/2" downpipes leading to a 3" Vibrant exhaust, this Audi has an exhaust note that puts both fear and excitement into those who are lucky enough to hear it. The owner reports that the car is pretty under tuned due to stock injectors, but more goodies are on the way in the form of a Vast stage 3 fueling kit. To top it all off it sits on Eibach coilovers and Hartman RS4 replica wheels.
