Muffler

Mufflers are integral components of a vehicle’s exhaust system, positioned downstream of the catalytic converter. Their primary function is to reduce exhaust noise via a series of chambers and baffles designed to induce destructive interference with sound waves. Construction typically utilizes heavy-gauge steel, often aluminized for corrosion resistance. Internal baffling designs—ranging from perforated cores to chambered plates—impact noise reduction levels and exhaust flow characteristics. Modern mufflers may incorporate resonance control features to target specific frequency ranges, and some designs prioritize backpressure for performance applications.
