Armytrix Car Exhausts for Audi RS4 (B8) 4.2L V8 FSI

The RS4 B8 was offered only as an Avant, with the high-revving naturally aspirated 4.2 FSI V8 and quattro drive with a crown-gear centre differential. It is the last RS4 with a non-turbo eight-cylinder, a fast estate with the character of a genuine sports car.

For the Audi RS4 (B8) 4.2L V8 FSI you will find a cat-back system by Armytrix, with Valvetronic silencers with remotely controlled valves.

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 systems are prepared to order: contact us for delivery times or if you have any doubt about compatibility with your car. All Armytrix exhausts for Audi are on their own page.
