The fourth-generation A-Class, the 2018 W177, brought the MBUX system to compact cars, with twin side-by-side screens and the 'Hey Mercedes' voice assistant. The A250 is the most powerful petrol version below the AMGs, with the 224 hp M260 2.0 turbo and seven-speed dual-clutch gearbox; this page covers front-wheel-drive A250s fitted with a petrol particulate filter (OPF).
For the Mercedes-Benz A250 2WD (W177) OPF (2019-), Armytrix offers the cat-back system with Valvetronic silencers and 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 Mercedes are on their own page.
