Audi R8 4S & 4S Facelift Racing Axle-Back Exhaust System by Remus

The Remus Racing Axle-Back Exhaust System for the Audi R8 and R8 Spyder is a track-focused performance upgrade engineered to deliver an aggressive motorsport sound and improved exhaust flow without the need for cutting the factory system. Constructed from 100% stainless steel with a shot-blasted finish, this rear-section exhaust retains the original vacuum-operated valve control via the vehicle’s onboard electronics for seamless integration. Designed as a direct fit using the OEM exhaust outlets, the system offers reduced back pressure, weight savings, and a purposeful racing character — built by hand in Austria to Remus’ renowned quality standards.

Please note: This is a racing product supplied without homologation and is not permitted for use on public roads.
