Milltek Sport (Audi, RS4 B9 2.9 V6 Turbo Avant, Non-OPF/GPF, 2018-2025) Exhaust System (Cat-Back)

Milltek Sport's Cat-Back exhaust system for the Audi RS4 (B9) 2.9 V6 Turbo Avant, Non-OPF/GPF, 2018-2025 replaces everything from the catalytic converter rearward, engineered to deliver genuine gains in flow, sound, and weight over the factory system. Constructed from T-304 stainless steel throughout, this system is built to outlast the car itself, resisting corrosion in a way mild steel factory systems simply can't.

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.
