Walker SoundFX Universal #18171 Universal Exhaust Muffler 2\" Inlet (OD) 2.5\" Outlet (ID) for Chevrolet C10

Constructed from 100% aluminized steel, the Walker SoundFX 18171 offers enhanced corrosion resistance and a longer service life compared to standard low-carbon steel options. It features an internal drainage system to mitigate moisture buildup, alongside internal partitions and mechanically joined tubes that flex during temperature changes to minimize housing distortion. The design incorporates spun-locked heads and louvered internal tubes, which effectively damp acoustic resonance to mimic original equipment (OE) quietness. As a universal component, it possesses expandable bushings for adaptable configurations, though specialized pipe fabrication or welding is typically necessary for installationty.Dimensional Specifications
