What Is the Remus Racing GPF-Back Exhaust System?

The Remus 081023 1510-5 is a full racing GPF-back exhaust system engineered for the BMW G80 M3 and G82 M4 platforms, including both standard and Competition models. It replaces the factory exhaust from the gasoline particulate filter (GPF) backwards, incorporating a racing sport exhaust, valve-controlled connection tubes, and a racing front silencer delete pipe. This design significantly enhances exhaust flow compared to the restrictive stock system.

Remus manufactures the entire system from high-grade, shot-blasted stainless steel, ensuring long-term durability even under demanding conditions. With larger 76 mm pipework (compared to the OEM 70 mm), the system maximizes flow efficiency to support tuned engines and spirited driving.
