The Dinan D660-0086-BLK Free Flow Axle-Back Exhaust is designed for 2020-2025 BMW X3M and X4M models using the F97/F98 chassis. The system uses T304 stainless-steel construction and is finished with black exhaust tips.

Dinan engineers the axle-back for a deeper, more aggressive exhaust note while maintaining controlled cabin sound. It is designed to pair with the Dinan D660-0087 resonator delete kit and Dinan intake components for a complete F97/F98 exhaust and intake package. Verify the exact vehicle configuration before ordering.
