BMW M3 Performance Exhaust — Dinan Axleback Free Flow, Black (2015–2020). A 304 stainless axle-back that delivers a deeper note and improved flow with factory-like fit.
Built to OE dimensions for stock hangers, dyno tuned to reduce backpressure. Twin computer-controlled 76 mm valves reuse the factory actuators to keep cruise volume in check and open under throttle; drone abatement tech preserves cabin comfort. Quad 3.5 in ceramic black, laser-engraved tips. About 3 lb lighter than stock with gains up to +5 hp.
