For more information, visit www.P65warnings.ca.gov.The Dinan Free Flow Axle-Back Exhaust (D660-0025-BLK) is a precision-engineered upgrade for the 2008-2013 BMW 135i/135is Coupe and Convertible (E82/E88). This system is designed to improve exhaust flow by effectively reducing back pressure, delivering a verified power increase of +6 HP and +5 LB-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 integrated drone abatement technologies that reduce cabin resonance. The design is also lighter than stock and built from 100% stainless steel to resist corrosion for years to come.
