Dinan Valved Axle-Back Exhaust - BMW X5 M / X6 M (F95/F96) 2020-2026 - Black Tips

The Dinan Valved Axle-Back Exhaust runs larger 83mm tubing versus the 80mm stock piping into a Dinan muffler that uses both absorptive and reactive technologies to cut backpressure while abating low-RPM drone. The factory exhaust valves and their actuators are retained, so tone still adjusts through the M-drive settings, staying civil at low speed and opening fully under load. Twin secondary 76mm valves are roughly 30% less restrictive than the OE units. Four 4.5in (114mm) double-walled, black ceramic-coated, laser-engraved tips fill the diffuser. Built from 100% T304 stainless steel, the system adds up to +6 HP and +5 lb-ft and installs bolt-on with the included hardware.
