Armytrix Valvetronic Cat-Back Exhaust - BMW M135 xDrive (F70)
A stainless valvetronic cat-back for the F70 BMW M135 xDrive with the B48 2.0-litre turbo. It includes a front pipe, mid-pipes and Armytrix valvetronic mufflers with quad 3.5-inch tips.
It plugs into the factory exhaust valve control, so the valves open and close with the drive modes you already use, with no extra controller needed. Armytrix also offers a True Wireless OBDII remote kit that adds on, off and auto modes at the push of a button.
Note: Works with the factory valve control, so no Armytrix control module is needed. Check fitment against your VIN before ordering. Installation by a professional is recommended.
