APR Catback Exhaust System with Center Muffler - 4.0 TFSI - C7 RS6 and RS7

The APR Catback Exhaust System personalizes your sound and performance. Beautifully hand-crafted T304-stainless-steel components adorn the system with stunning TIG-welding throughout. Our straight-through brushed-finished mufflers smooth the exhaust note to a deep growl, without adding restrictions. Strong high-quality bracketry and OEM-style clamps hold the system steadily in place, making the install or removal a snap, and fitment simple, yet precise. Cast 2.75” to dual 2.5” rear splitter creates an ultra-smooth transition, steadily feeding exhaust gasses out of the system. Our cast valve housings enable the vehicle to be fitted with the factory electronic valve actuators, retaining OEM valve operation. An optional center muffler / Center muffler delete is available.
