Milltek 80mm Non-Resonated Signature Series Axle-Back Exhaust - Audi RS6 RS7 C8 - Cerakote Black Oval Tips - SSXAU1049

Milltek 80mm Cat Back Non-Resonated Signature Series Axle-Back Exhaust for the Audi RS6 C8 and RS7 C8. Direct factory fitment using OEM hangers and mounting points - no modification required. Hand-finished T304L stainless steel construction with Cerakote Black oval tips delivers aggressive full-throttle character without resonance buildup on closed-course or track applications.

Engineered for the twin-turbo 4.0L engine (EA898), this non-resonated design eliminates mid-range drone points while preserving the V8 engine note at peak throttle. Mandrel-bent primary bends and secondary resonance chamber deletion create a direct path to maximum sound character. Fully welded construction and precision CNC-formed hangers ensure OEM+ durability and alignment.
