Cat-Back Exhaust (Resonated for Performance Catalyst).
The best just got better. 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.
The Touring Edition Exhaust comes complete with 180 Technology® resonators, a precision-engineered x-pipe, resonated downpipes, and your choice of 90 or 102mm tips in either diamond black or chrome silver, All tip options include the AWE logo, and double walling to ensure a mirror finish even under hard usage. All tips are individually adjustable, allowing depth into the bumper to be set according to personal taste..
