We developed a new axleback exhaust with built in resonators for BMW F80 M3 & F82 M4, most straight through chamber design exhaust tends to have cabin drone sound under 3000 RPM during highway cruising speed.

Our R&D technician added additional resonators on each side of exhaust to absorbed and eliminated the cabin drone sound for low RPM driving.

Expect to release in Spring 2021, Please stay tune for new shipment updates !
