Megan Racing Supremo Exhaust for BMW F8X M3/M4 ECSTuning
Details on fitment and pricing here! Megan Racing Supremo Exhaust for BMW F8X M3/M4 Megan Racing’s Axle-Back Exhaust Systems for the F8x M3/M4 replaces the typically quiet and restrictive factory muffler and exhaust components with a larger, free flowing straight-thru type muffler. Megan Racing’ Supremo Exhaust system utilizes straight-thru perforated glass-pack mufflers dramatically decreasing exhaust backpressure as the gasses are allowed a straight, unrestricted passage while sound frequencies are absorbed by the glass-pack fiber material providing a nice, mellow tone.
