Walker Quiet-Flow SS 21481 Direct Fit Exhaust Muffler 2.5" Inlet (ID) 2.5" Outlet (ID) for Chevrolet Colorado

Designed to fit Chevrolet Colorado models from 2004 through 2011, the Walker Quiet-Flow SS 21481 exhaust muffler features 2.5" inlet and outlet diameters.

Crafted entirely from stainless steel, this muffler offers superior corrosion resistance compared to aluminized models and includes an internal drainage system to minimize moisture buildup. Its internal partitions and mechanically joined tubes accommodate thermal expansion to prevent distortion, while spun-locked heads and OE-style spot welds enhance durability and stability.

The direct-fit design incorporates OE-style hangers, brackets, and pipe routing for easy, bolt-on installation without the need for welding or custom fabrication. Premium acoustic features such as OE-style louvered tubes and domed heads reduce noise transmission for authentic factory sound quality. Tested acoustically and for flow, this muffler delivers reliable OE-style performance.
