Dinan Free Flow Axleback Exhaust - Black Tips - BMW E90 M3

Dinan free flow axleback exhaust for the BMW E90 M3 uses a single-channel straight-through canister design to reduce exhaust restriction on the S65 V8, adding 6 HP and 5 lb-ft at 6800 RPM. At 10 lbs lighter than the factory part, the Dinan exhaust installs on the stock brackets and hangers for a factory-fit installation without cutting or welding. A Helmholtz chamber suppresses cruise-speed drone for everyday livability.

Quad 3-inch black ceramic-coated and laser-engraved exhaust tips deliver an aggressive visual presence and a sportier exhaust note at full throttle while remaining refined at light throttle, consistent with Dinan performance philosophy. 100% 304 stainless steel construction.
