Milltek Non-Resonated US-Spec Cat-Back Exhaust - Audi B8 RS5 - OE Tips - SSXAU335

The Milltek Race Non-Resonated Cat-Back Exhaust System is engineered as a direct factory replacement for the Audi B8 RS5 (2010-2015, 4.2L V8). This system delivers maximum sound character and performance flow with OEM fitment-no modification required.

Constructed from T304L stainless steel and mandrel-bent throughout, this cat-back features a 2.76" (70mm) pipe diameter for optimized exhaust velocity. The non-resonated design eliminates the factory resonance chamber, producing an aggressive, full-throttle tone while retaining premium sound quality. Uses OEM exhaust tips and hangers for seamless integration.
