    Quiet the drone and keep your exhaust flowing with the Walker Exhaust Quiet-Flow Muffler Assembly (MPN 54637), an aluminized, direct-fit bolt-on muffler that damps combustion noise for OE-style sound. It drops in for the 2004-2009 Dodge Ram 2500 and Dodge Pickup Ram 2500 3/4 Ton, the 2004-2009 Dodge Pickup Ram 3500 1 Ton, and the 2004-2007 Dodge Ram 3500 — see the "Vehicles it fits" section for engine-level coverage.

    • Premium acoustic control: OE-style louvered tubes lower noise levels while OE-style domed heads help reduce radiated noise for factory-style sound quality compared to straight perforated tubes.
    • Built to last: internal partitions and mechanically joined tubes allow expansion and contraction during temperature changes to minimize distortion, while spun-locked heads and OE-style spot welds add stability and longer service life.
    • Resists corrosion: an internal drainage system helps reduce moisture collection inside the shell.
    • Easy to install: a direct-fit bolt-on solution with factory-style hangers, brackets and pipe routings — no specialized fabrication or welding required.

    This exhaust muffler assembly has a 4" inlet (ID) and 4" outlet (ID), both offset. Backed by Walker's limited lifetime warranty and 90-Day Safe and Sound guarantee.
