This RACING Downpipe-Back Titanium Sport Exhaust (SKU: 081021 1510TI-3) is engineered for BMW M3/M4 Competition Touring (G234M, 2021+) models, compatible with both GPF and non-GPF configurations. The system replaces the factory exhaust from the downpipe back with high-flow 76mm titanium tubing and integrated valves that maintain operation through the vehicle's original actuators and electronics. Handcrafted in Austria from full titanium construction, this exhaust delivers aggressive racing sound, performance gains through reduced back pressure, and significant weight reduction. Unlike other systems, this downpipe-back version requires no cutting of the original exhaust. The system carries no EEC/ECE approval and is intended exclusively for closed-course racing use.
