In the G22 4 Series Coupé, the four-cylinder versions are the 420i and 430i, both with the B48 2.0-litre turbo in different outputs and paired with the eight-speed automatic. European cars have a gasoline particulate filter, required by the latest Euro 6 rules: this page is dedicated to them.
For the BMW 420i/430i (G22) B48 OPF Coupé (2021-), Armytrix offers the cat-back system with Valvetronic silencers and downpipes. Tips are available in chrome silver, blue coated, matte black, carbon and gold. 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.
