Overview
Upgrade the Audi RS3 Saloon / Sedan 400PS - Non-OPF/GPF Models (2017+) with a Milltek Sport cat-back exhaust. Milltek builds each system around the car it fits: mandrel-bent T304L stainless pipework, a larger bore than stock for freer flow, and a tuned sound you choose, from quiet and refined to loud and uncorked.
Sound options
- Resonated options keep cruising drone down and sound closer to a refined sports car.
- Non-resonated (louder / race) options give the loudest, rawest note. Better for track days and weekend cars than daily commuting.
Choose your setup
- Sound: the system type and sound level.
- Tip Finish: the tailpipe trim.
- Optional Downpipe: add a Milltek catted or catless downpipe built to fit this cat-back. Pick Cat-Back Only to skip it.
