Audi S1 Armytrix Valvetronic Catback Exhaust System

Made of high quality T304 stainless steel, this Armytrix catback exhaust system, intended for the Audi S1, features active valves (valvetronic) allowing the exhaust tone level to be adjusted via remote controller or mobile application. Very aggressive while valves are open, this exhaust remains comfortable with closed valves, offering anyway a unique looking thanks to its 3.5" / 90mm tailpipe set available with chrome, black or blue titanium finish. Delivered ready to install with instructions and assembly hardware, Armytrix exhausts have a finish, manufacturing quality and exclusive sound, making the brand a benchmark in the premium segment.
