Dinan Valved Axleback Exhaust - BMW X5 M (F95)/X6 M (F96) - Black Tips
Dinan has spent decades refining BMW performance parts in the United States, and this axleback exhaust is built to give the BMW X5 M and X6 M the voice their size and power deserve. Retaining the factory electronic valve control, it lets you toggle between a civilised cruise and a properly aggressive bark under load.
This listing covers the BMW X5 M (F95) and BMW X6 M (F96), fitted with black ceramic coated tips. The system bolts on using the retained OE valve actuators, so no tuning or recalibration is required to operate the valves via the standard M-drive settings.
Specifications
- 304 stainless steel construction, TIG welded and brush finished
- 83mm mandrel bent piping (up from 80mm stock) for improved flow
- Twin 76mm secondary valves, around 30 percent less restrictive than OE
- Quad 114mm (4.5 in) double walled, black ceramic coated, laser engraved tips
- Maximum gains of approximately 4.5kW (6 hp) and 6.8Nm (5 ft-lb)
- Includes mounting hardware for factory style fitment
Vehicle compatibility, OEM part numbers, and fitment notes are provided in the tabs above. Please confirm your X5 M or X6 M's build year and configuration before ordering.
