BMW M135i F40 Armytrix Valvetronic Catback Exhaust System

Made of high quality T304 stainless steel, this Armytrix catback exhaust system, intended for the BMW M135i F40, features active valves (valvetronic) allowing the exhaust tone level to be adjusted via remote controller or app. Very aggressive while valves are open, this exhaust remains comfortable with closed valves, offering anyway a unique looking thanks to its 4" / 101mm tailpipe set available with chrome, black, carbon fiber or blue titanium finish. Delivered ready to install with instructions and assembly hardware, Armytrix exhausts have a finish, manufacturing quality and an exclusive sound, making the brand a benchmark in the premium segment.
