Overview

Milltek Non-Resonated Cat-Back Exhaust System for the Audi B8.5 S5 Coupe and Cabriolet (3.0 TFSI). Direct factory fitment using OEM hangers; no modification required. Replaces the complete cat-back section from the secondary catalytic converter rearward.

Constructed from T304L stainless steel with 2.37" (60.30mm) mandrel-bent piping. Hand-finished polished quad outlet trims. The non-resonated design eliminates the OEM resonance chamber, delivering an engineered tone that emphasizes full-throttle character without drone at cruise. Uses the factory valve location for OEM valve compatibility where equipped.
