Under the bonnet of a G20 or G21 320i or 330i you may find either the B48 or the B46, a variant of the same 2.0-litre turbo four used in certain markets. You cannot tell from behind the wheel, but the two engines do not share every component, so it is worth checking the code in the car's documents before ordering. This page covers B46 3 Series cars without a particulate filter.
For the BMW 320i/330i (G20/G21) B46 Non-OPF Sedan/Touring (2019-), 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.
