Description
Milltek Resonated Cat-Back Exhaust System for Audi D4 S8 Quattro. Direct factory fitment cat-back system engineered to replace the OEM exhaust with improved flow dynamics and refined sound character. Mandrel-bent T304L stainless steel construction with hand-finished titanium trim options.
The resonated design eliminates drone at cruise while preserving full-throttle character on hard acceleration. 2.76" (70mm) bore optimizes scavenging for the D4 platform's naturally aspirated engine. Uses OEM hangers and mounting points-no modification required. CNC-formed junctions and precision welding throughout.
Fitment & Compatibility
- Audi D4 S8 Quattro (2013-2018)
- Direct cat-back replacement-turbo, downpipe, and secondary cats remain factory
- Requires no ECU tune or modification
- Compatible with OEM valve systems
Every system is dyno-tested and EC-approved for road use, offering proven gains in flow efficiency and engineered tone without compromise to drivability.
Designed and manufactured in the UK with 40+ years of performance exhaust heritage. Tested at the Nurburgring.
