MagnaFlow XL 3 chamber mufflers use a unique combination of large-diameter perforated tubing and strategically placed sound baffles to reduce unwanted resonance and help 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 reflect off the back wall of the muffler and cancel out unwanted harsher sounds. The large-diameter perforated core eliminates the flow restrictions of a louvered-style core. A careful balance between perforation size/spacing and the baffle tuning gate makes for great 3-chamber performance mufflers.

Magnaflow Exhaust products are covered by a lifetime warranty from defects. Most mufflers are warranted against blowouts and defects in material and workmanship for as long as the original purchaser owns the vehicle in which they were originally installed. Magnaflow's XL Series mufflers/exhausts, catalytic converters, and titanium exhaust line carry a limited warranty. This warranty is voided when any muffler has been installed on any commercial or racing vehicle, or has been improperly installed, altered, subjected to misuse, or damaged from accidents. The cost of labor and any additional parts required to complete the installation of a replacement muffler are not covered.
