On the G02 X4 too, the xDrive20i and xDrive30i can carry the B46 instead of the B48: two variants of the same 2.0-litre turbo four, used depending on the market. The cars look and drive the same, so before choosing engine parts it is worth reading the code in the vehicle documents. This page covers B46 X4s without a particulate filter.
For the BMW X4 (G02) xDrive20i/xDrive30i B46 Non-OPF (2019-2025), Armytrix offers downpipes. 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.
