The sporty Cat-back exhaust system from Armytrix is dedicated to the BMW M135i F20/F21.
The entire system is made of T304 stainless steel alloy. The system ends with single, polished tips, and optionally with matte black or blue Titanium style. No modifications are required for the installation of this system; it is perfectly fitted to the car. Optionally, the exhaust can be expanded with a high-flow de-cat downpipe or dual tips.
Armytrix exhaust systems are the perfect solution for those seeking uncompromising acoustic experiences. Regardless of whether there are inline 4 cylinders or 8 cylinders in a V configuration under the hood, this exhaust will bring out the most powerful engine sound. Thanks to the use of a remote-controlled valve system, the car does not lose its practicality and can change its character depending on the driver's mood.
All Armytrix exhaust systems are equipped with a remote-controlled valve system that allows sound adjustment via a wireless remote or smartphone app.
The Armytrix app is a necessary and revolutionary extension of the ValveTronic exhaust system's functionality. We set ourselves the goal of enhancing the driver's connection with their car through improved functionality and mobility. By receiving current engine operating parameters, you can always keep your finger on the pulse. Control the valve settings through a simple digital interface.
The current valve setting is displayed through a simple and clear interface. When the light is green, the valves are open. The red light indicates the valves are closed, while the orange light indicates automatic mode in which the valves open at 3500 RPM.
