BMW 135is Performance Exhaust - Rear - Dinan - Axle Back, Freeflow - Black - 2013. Dinan’s axle-back system adds a deeper, sportier tone and improved flow for the 135is while preserving daily comfort.

Built from 100% 304 stainless steel to Dinan specifications, this Free Flow exhaust reduces back pressure and weight compared to stock, delivers verified gains, and mounts using the factory brackets and hangers. Dual 3.5" laser-engraved ceramic black tips provide a purposeful finish, while drone abatement technologies curb cabin resonance at cruise and let the exhaust open up under throttle. Compatible with E82/E88 2008–2013 135i/135is.
