The first X4 to wear the full M badge, the F98 stands out from the X3 M through its sloping roofline while sharing its engine and drivetrain. The 2021 update brought redesigned headlights, the forged crankshaft from the G80/G82 M3 and M4 and 650 Nm of torque for the 510 PS Competition, still with M xDrive and an eight-speed automatic.
For the BMW X4 M (F98) Electric Valve Non-OPF (2019-2025), Armytrix offers the cat-back system with Valvetronic silencers and downpipes. Tips are available in chrome silver, blue coated, matte black and carbon. Versions without a catalyst are for track use only.
Armytrix systems are made in Taiwan in T304 stainless steel and titanium. At their heart is the valve in the silencer, opened and closed on command from the remote or the app, with a module that plugs into the car's OBD port. Armytrix exhausts are not road approved in the European Union or Switzerland: they are intended for track use.
Armytrix systems are prepared to order and the price is on request: contact us for a quote, for delivery times or if you have any doubt about compatibility with your car. All Armytrix exhausts for BMW are on their own page.
