Part #: D660-0054A

The F85 X5M and F86 X6M are the quintessential SUV in terms of power and performance with accolades in numerous periodicals crowning them the pinnacle of their class. With the possibility of putting down over 700 HP with a base tune, these vehicles are no slouch. Dinan engineers wanted to match this impressive feat with an equally impressive exhaust tone that let those around these SUV's hear the power that lies beneath the hood as well as be able to show it.

  • 8 HP @ 6000 RPM, 7LB-FT @ 6000 RPM
  • Quad 89mm (3.5")polished or cermic black laser engraved exhaust tips
  • Enjoyably louder, sportier sound with a deep growl
  • Helmholtz chamber to reduce drone
  • Computer controlled valve limits noise during low speed driving; valve opens fully during high-load conditions to allow free flow
  • 100% 304 stainless steel construction
  • Uses the factory brackets and hangers for a factory-like fitment
