Description

The Walker Exhaust 21525 Quiet-Flow SS muffler is a direct-fit replacement designed for select Chevrolet Cobalt and Buick LaCrosse/Allure models. Constructed from 100% stainless steel, it offers enhanced durability and corrosion resistance compared to aluminized mufflers. This muffler features OE-style internal partitions and mechanically joined tubes to minimize distortion from temperature changes, and spun-locked heads and OE-style spot welds for stability.
