The Dinan Free Flow Axle-Back Exhaust replaces the factory rear muffler section with a single channel, straight through canister built entirely from 100% T304 stainless steel. It weighs 10 lbs less than the stock BMW assembly and adds 6 hp and 5 lb-ft at 6,800 rpm, while an internal Helmholtz chamber cancels the cruising drone typical of free flowing systems. The system exits through quad 3 in black ceramic coated, laser engraved tips and hangs from the factory brackets and hangers for a stock-like fit.
