AWE Tuning Touring Edition Exhaust is a performance upgrade for the Audi B9 S4 designed to enhance the vehicle's sound profile. It removes the stock exhaust valves and replaces them with AWE's 180 Technology® resonators and electronic valve simulators. This system offers a balance between a refined cabin noise during cruising and a more pronounced exhaust note with pops and burbles during acceleration and downshifts.
