• Twin secondary exhaust valves feature an impressive 76mm diameter, reducing restriction by 30% compared to OEM valves
• Computer-controlled exhaust valves retain full functionality for dynamic sound control

Premium Construction:

Intelligent Valve Control:

The system reuses stock exhaust valve actuators and maintains original valve operation, allowing drivers to adjust exhaust tone through the vehicle's M-drive settings. Valves remain closed during low-speed driving to limit noise, then open fully under high-load conditions to unleash the full exhaust note.

This axle-back exhaust system delivers a sportier, more engaging sound without sacrificing refinement, making it an ideal upgrade for enthusiasts seeking both performance and versatility.
