With the facelift of the F30 and F31 3 Series, the 320i and 330i moved to BMW's new modular 2.0-litre turbo four. In Europe it is the B48; the B46 is its version for markets with stricter emissions limits, such as the United States, mechanically almost identical but with different emissions-control hardware. Rear-wheel or xDrive all-wheel drive, saloon or Touring.
For the BMW 320i/330i (F30/F31) B46 Sedan/Touring (2015-2018), 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.
