Fits 2020-2026 BMW X5 M and X6 M (including Competition models).

The Dinan Freeflow Axleback Exhaust System for the F95 X5 M and F96 X6 M is engineered to improve exhaust flow while delivering a refined, aggressive tone. By increasing the tubing diameter to 83mm (up from the factory 80mm), this system reduces backpressure and optimizes performance. The 100% 304 stainless steel construction ensures long-term durability and corrosion resistance.

This system retains the factory computer-controlled exhaust valves, allowing the exhaust tone to be adjusted via the vehicle's M-drive settings. The secondary valves feature a massive 76mm diameter—30% larger than stock—to maximize flow and sound volume under load. Dinan’s proprietary drone abatement technology and reactive muffler design ensure the cabin remains comfortable and intimate during low-speed cruising.

  • 100% 304 stainless steel construction
  • 83mm diameter piping for increased flow (vs. 80mm stock)
  • Four 4.5" (114mm) double-walled, black ceramic-coated tips with laser-engraved logos
  • Retains factory computer-controlled exhaust valve operation (reuses stock actuators)
  • Twin 76mm secondary exhaust valves
  • Performance gains: +6 HP and +5 lb-ft torque
  • Engineered with drone abatement technology to reduce cabin resonance
  • Factory-like fitment with included mounting hardware
  • MPN: D660-0090-BLK
