Magnaflow XL 3 Mufflers use a unique combination of large diameter perforated tubing and strategically placed sound baffles to reduce unwanted resonance and helps your engine create horsepower. The sound baffles tune the sound waves using calibrated tuning gate openings that allow portions of the waves to pass through. These tuned waves in turn reflect off the back wall of the muffler and cancel out unwanted harsher sounds.
