Milltek Sport Audi RS3 Saloon/Sedan 8Y (OPF/GPF) 2021-2025 GPF-Back Exhaust System

Milltek Sport's Particulate GPF-back exhaust for the Audi RS3 Saloon/Sedan 400PS (8Y MQB EVO), OPF/GPF, 2021-2025, replaces everything from the gasoline particulate filter rearward, engineered to deliver genuine gains in flow, sound, and weight over the factory system while retaining the OPF/GPF unit itself for continued emissions compliance. Constructed from T-304 stainless steel throughout, this system is built to outlast the car itself, resisting the corrosion that eventually catches up with mild steel factory systems.

Milltek's own sound engineers spend considerable time tuning each system's resonance and tone, striking a genuine balance between a purposeful, sporting character and everyday drivability, avoiding the drone that can plague poorly engineered aftermarket systems on a long motorway drive. Because this system works around the retained OPF/GPF unit, it's specifically engineered to deliver a genuine performance and sound upgrade while keeping the particulate filter's emissions function intact.

Please select your type at checkout: Race Non Resonated, Non Resonated, or Resonated. Resonated offers the most refined, restrained everyday character, Non Resonated delivers a noticeably louder, more aggressive tone, and Race Non Resonated is the most extreme option, best suited to track use.
