Optimized Flow and Sound: Featuring a larger 3.5'' single midpipe and 2.75'' diameter piping to enhance flow, improve throttle response, and deliver a sportier exhaust note.
Advanced Valve System
Dual Valve Setup: Converts the factory single-valve system into a dual-valve design, akin to M-series cars. This upgrade ensures even flow and better sound management regardless of valve position.
Retains OEM Controls: The stock exhaust valve actuator is repurposed, and an additional valve/actuator is integrated on the opposing side. The system works seamlessly with your vehicle’s cabin controls, maintaining quiet operation in Comfort mode and unleashing full performance in Sport mode.
