With the G02 X4, BMW confirmed its recipe for a mid-size SUV coupé: X3 mechanicals, a sleeker shape and a lower centre of gravity. The xDrive20i and xDrive30i use the B48, a 2.0-litre turbo four paired with the eight-speed automatic; this page covers cars without a gasoline particulate filter.
For the BMW X4 (G02) xDrive20i/xDrive30i B48 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 builds its exhausts in Taiwan, in T304 stainless steel and titanium, and is one of the brands that made valved exhausts affordable: the valve sends the gases through the silencer or around it, and it is controlled with the supplied remote or a smartphone app through a module plugged into the 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.
