Description
The Milltek 80mm Race Non-Resonated Cat-Back Exhaust is engineered for the Audi 8Y RS3 (2021+) as a direct OPF/GPF-back system. This is our loudest cat-back option, delivering maximum volume enhancement with race-spec performance.
Constructed from T304L stainless steel and mandrel-bent for optimal flow, this system features a race-spec rear silencer for reduced weight and aggressive exhaust character. Direct factory fitment uses OEM hangers-no modification required. The 80mm (3.15") large bore diameter maximizes scavenging and supports peak power delivery across the RPM range.
Fitment & Compatibility
- Audi RS3 8Y Saloon/Sedan (2021+)
- OPF/GPF-back configuration

- Non-resonated design for closed-course/track use
Every system is dyno-tested and engineered for measurable flow improvement alongside authentic sound character.
Designed and manufactured in the UK with 40+ years of performance exhaust heritage. Tested at the Nurburgring.
