Milltek Sport (Audi, RS4 B8 4.2 FSI Quattro Avant) Exhaust System (Cat-Back)

Milltek Sport's Cat-Back exhaust system for the Audi RS4 (B8) 4.2 FSI Quattro Avant 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.
