The sporty Cat-back exhaust system from Armytrix is dedicated to the Audi RS4 Avant B9 2.9 TFSI.
The entire system is made of T304 stainless steel alloy. No modifications are required for the installation of this system; it is perfectly fitted to the car. The exhaust valves are controlled via the Armytrix control system using a wireless remote. Optional exhaust tips: matte and chrome. There is an option to purchase a downpipe de-cat with a ceramic coating.
Armytrix exhaust systems are the perfect solution for those seeking uncompromising acoustic experiences. Whether there are 4 inline cylinders or 8 cylinders in a V configuration under the hood, this exhaust will bring out the most authentic engine sound. By utilizing 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 for 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 increasing the driver's connection with their car through improved functionality and mobility.
