This RACING Secondary Cat-Back Titanium Sport Exhaust (SKU: 081021 1510TI-2) is engineered for BMW M3/G81 Competition Touring (G234M, 2021+) models, compatible with both GPF and non-GPF configurations. The system features high-flow 76mm titanium tubing that replaces the factory 70mm piping, with integrated valves operated through the vehicle's original actuators and electronics. Handcrafted in Austria from full titanium, this cat-back system delivers aggressive racing acoustics, reduced back pressure for performance gains, and significant weight savings. Installation requires cutting the original exhaust and is intended solely for closed-course racing use, as it carries no EEC/ECE approval for public roads.
