Show original supplier description
The ARMYTRIX Valvetronic Cat-Back Exhaust System is engineered for the BMW E90, E92, and E93 M3 models produced between 2007 and 2013, specifically for vehicles equipped with the 4.0L S65 V8 engine. Experience unparalleled sound control with ARMYTRIX's Valvetronic technology. This system features an app-controlled valve system that integrates with your vehicle's OBDII port, allowing you to seamlessly switch between different sound modes—Smart, Neighbor, and Beast—with the push of a button or via a customizable automatic setting. This technology not only enhances the driving experience but also helps retain low-RPM torque by managing backpressure when the valves are closed, while opening them allows for freer exhaust flow and increased sound output. An important note for E93 Convertible models is that a special bracket is required, which must be specified when ordering. Additionally, the ARMYTRIX OBDII Control Module is a required component for the operation of this exhaust system.
