Description
Milltek Non-Resonated Cat-Back Exhaust System for Audi D4 S8 Quattro. Direct factory fitment replacement using OEM hangers and mounting points-no modification required. T304L stainless steel, mandrel-bent construction with CNC-formed collector and tail section.
The non-resonated design delivers a full-throttle character without secondary resonance chambers, engineered for closed-course and track environments. 2.76" (70mm) bore maximizes exhaust scavenging across the 4.2L FSI power band. Cerakote Black-finished stainless tips resist thermal discoloration. Hand-finished welds meet OEM+ tolerances.
Fitment
- Audi D4 S8 Quattro (2013-2018)
- 4.2L FSI V8 (not compatible with hybrid models)
- Cat-back configuration (catalytic converter rearward)
- Uses OEM mounting hardware and resonance isolation points
Milltek cat-back systems are dyno-proven to preserve OEM throttle response while optimizing mid-range torque delivery. Hand-finished stainless and precision mandrel bending eliminate weak flow points competitors accept as standard.
Designed and manufactured in the UK with 40+ years of performance exhaust heritage. Tested at the Nurburgring.
