Dinan 11-16 BMW 550i xDrive Freeflow Axleback Exhaust System - Black

Dinan's Free Flow Axle-Back Exhaust improves exhaust flow by reducing back pressure, resulting in increased power output and a great sporty sound that is civilized when you want it to be and pleasantly aggressive under harder acceleration with zero drone. 100% stainless steel construction and exacting specifications ensure that the system fits correctly using the factory hangers and will resist corrosion for years to come. A vacuum controlled butterfly valve is utilized to improve flow at wide-open throttle while keeping things civilized and "drone" free throughout. The design reduces overall weight as well and features 3.5'' polished, or ceramic black, tips for a tasteful high-performance look.

Installation Instructions
  • Quad 3.5" laser engraved, polished or ceramic black exhaust tips
  • Uses the factory brackets and hangers for a factory-like fitment
  • Drone abatement technologies used to reduce cabin resonance
  • More Power: + 10 HP when coupled with engine software
  • 100% 304 stainless steel construction
  • Enjoyably louder, sportier sound
