BMW 550i xDrive Performance Exhaust - Dinan - Freeflow Axleback - Polished - 2011–2016. An axle-back system that improves flow and delivers a sporty, refined tone with zero drone.
Built for the F10 550i xDrive, Dinan’s Freeflow Axleback is 100% 304 stainless steel and bolts to factory brackets and hangers. A vacuum-controlled butterfly valve boosts flow at wide-open throttle while keeping cabin resonance down at cruise. Quad 3.5" polished, laser-engraved tips finish the system, and the design is lighter than stock. Pair with appropriate engine software for gains up to +10 hp.
