Milltek Race Non-Resonated Cat-Back Exhaust - Audi B8 S5 - Polished Tips - SSXAU357

The Milltek Race Non-Resonated Cat-Back Exhaust System is engineered for the Audi B8 S5 3.0 TFSI Coupe and Cabriolet. This 2.37" (60.30mm) dual outlet system replaces the factory cat-back with direct fitment using OEM hangers, requiring no modification.

Constructed from hand-finished T304L stainless steel with mandrel-bent piping, this system delivers aggressive full-throttle character with minimal interior drone through precision acoustic tuning. Polished oval trim finishes provide OEM+ visual integration. Non-resonated configuration is engineered for closed-course and track use where peak exhaust note is prioritized over street refinement.
