Free up your BMW G8X M2, M3 or M4's S58 twin-turbo inline-6 with these EPA-compliant 400 cell high-flow catted downpipes, built to reduce backpressure and sharpen exhaust character while maintaining emissions compliance standards.
The G8X M2, M3 and M4 represent the next evolution of M performance, powered by the highly capable S58 twin-turbo inline-6. While the factory catalysts prioritise restriction and sound suppression, these EPA-compliant 400 cell high-flow catted downpipes reduce exhaust backpressure, enhance turbo efficiency and unlock a sharper, more aggressive exhaust character, all while maintaining emissions compliance standards. This upgrade maximises the performance potential of the S58 platform without compromising drivability.
