Meet the perfected B9 S4 soundtrack. Signature AWE howl, delivered. The Touring Edition is the sophisticated member of the B9 S4 exhaust family. The Touring Edition Exhaust removes the factory valving and replaces it with AWE’s 180 Technology® drone-cancelling resonators (and electronic valve simulators). This solution provides for a perfect, signature AWE experience: civil within the cabin while cruising, yet all the pops and burbles during acceleration and downshifts.
