Milltek Sport Audi RS3 Sportback 8V (Facelift Only) Cat-Back Exhaust System

The RS3 Sportback'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 facelift-only models.

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 eight finishes, four round tip options, Cerakote Black, Polished, Titanium, and Burnt Titanium, and the same four finishes again in an oval tip shape. All tip options deliver identical performance and sound characteristics, purely a styling choice.
