Milltek Sport Audi RS3 8V 2017+ (OPF/GPF) Cat-Back Exhaust System

The RS3's turbocharged five-cylinder is genuinely one of the most distinctive engine notes on the market, and the factory exhaust, while far from bad, leaves real character on the table, tuned as much around noise regulations as outright drama. Milltek Sport's Cat-Back exhaust replaces everything from the catalytic converter rearward, engineered to deliver genuine gains in flow, sound, and weight over the factory system, specifically for OPF/GPF-equipped models from 2017 onward.

Constructed entirely from T-304 stainless steel, this system is built to outlast the car itself, resisting the corrosion that eventually catches up with mild steel factory systems, especially through wet European winters. Milltek's own sound engineers spend considerable time tuning each system's resonance and tone, letting that five-cylinder warble come through properly without tipping into drone on a long motorway drive.

Please select your type at checkout: Resonated (the most refined, restrained everyday character), Non-Resonated (noticeably louder and more aggressive), or Race Non-Resonated (the most extreme option, best suited to track use).

Please select your exhaust tip finish at checkout: available in Black, Polished, Titanium, or Burnt Titanium finish, in either standard round tips or an oval tip shape depending on the type/finish combination selected. All tip options deliver identical performance and sound characteristics, purely a styling choice.
