Constructed entirely from 100% stainless steel, this muffler offers superior corrosion resistance compared to traditional aluminized mufflers, ensuring a longer service life. The internal drainage system effectively reduces moisture accumulation, mitigating the risk of rust and extending the muffler's longevity. Measuring 18.00 inches in body length, with a 2.00-inch inlet and outlet diameter, and an overall length of 22.00 inches, the 21813 is engineered for a precise fit in a variety of vehicle applications. Its oval shape allows for optimal space utilization and efficient exhaust flow. The muffler features OE-style louvered tubes that effectively lower noise levels, while the OE-style domed heads help reduce radiated noise, delivering a premium factory-style sound quality. The internal partitions and mechanically joined tubes allow for expansion and contraction during temperature changes, minimizing distortion and enhancing structural stability. Spun-locked heads and OE-style spot welds further contribute to the muffler's durability and performance.
