In the early years of the 4 Series, the F32 coupé and the F33 convertible with its folding hardtop offered the 420i and 428i with the N20 2.0-litre turbo four, rated at 184 and 245 PS. In the United States, the 428i sold in states with SULEV rules, the low-emissions category defined in California, used the N26 variant.
For the BMW 420i/428i (F32/F33) N26 Coupé/Cabriolet RWD (2014-2015), Armytrix offers downpipes. 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.
