Manufacturer specifications
Our Axle-Back Exhaust Systems for the G20 3-Series replaces the typically quiet and restrictive factory muffler and exhaust components with a larger, free flowing straight-thru type muffler. Whereas OEM muffler constructions typically rely on multiple chambers to bounce and absorb sound frequencies. This results in the increase of backpressure as exhaust gasses are deflected back and forth robbing engine response and power. Megan Racing Supremo Exhausts system utilize 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. Comprised of 100% T-304 stainless steel, Megan Racing exhaust components are designed to last the test of time and protected with a 1-year warranty against manufacturer defects. Off-Road Use Only.
NOTE: The OEM muffler must be cut off in order to install this system using the provided slip on clamps.
