For more information, visit www.P65warnings.ca.gov.The Dinan Free Flow Axle-Back Exhaust (D660-0048-BLK) is an engineered performance solution for the 2014-2016 BMW M235i (F22), specifically designed for vehicles equipped with the M-Performance rear valance. Dinan engineers have optimized the system to improve exhaust flow by reducing back pressure, delivering a verified power increase of +6HP and +5LB-FT of torque at 6600 RPM. The result is a great sporty sound that is pleasantly aggressive under hard acceleration yet remains civilized thanks to an integrated Helmholtz chamber design that specifically reduces resonance or "drone" at low RPM.
