Armytrix Mercedes-AMG W177 A35 (2019-Present) valvetronic exhaust system
Transform your AMG hatchback with the ARMYTRIX Valvetronic Exhaust System for the Mercedes-AMG A35 (W177) 4MATIC+ (2019–Present). Developed for the M260 2.0L turbocharged engine, this system delivers the exhilarating sound and throttle response the A35 was meant to have—complete with wireless valve control, Dynamic Select integration (pre-facelift), and compatibility with OPF and Non-OPF models.
Built with precision 2.75” mandrel-bent piping and finished in bold quad carbon fiber oval tips, the ARMYTRIX system gives your A35 an unmistakable AMG roar and race-inspired presence—while helping to suppress Check Engine Lights (CEL) with built-in fault-code clearing for catalytic and OPF systems.
