AWE Tuning Track Edition Cat-Back Exhaust for 2015-2020 BMW M3/M4 - 102mm Diamond Black Tips (3020-43087)

Fits 2015-2020 BMW M3 and M4 (F8X) Base, CS, and GTS models. This system is designed for enthusiasts seeking a raw, aggressive exhaust note and maximum weight reduction by replacing the valved rear muffler with a straight-through configuration.

The AWE Track Edition Cat-Back Exhaust provides a constant "valve open" sound profile for the S55 engine, utilizing a precision-engineered X-pipe to smooth out the tone while increasing volume. Handcrafted at AWE's headquarters from U.S.-sourced 0.065-inch wall T304L stainless steel, this 3-inch CNC mandrel-bent system offers a significant 22.5lb weight savings compared to the factory exhaust. To ensure seamless integration, AWE includes mechanical valve simulators that allow the factory exhaust valve motors to remain plugged in, preventing electronic faults.
