Description

Keep exhaust noise in check and fight rust for the long haul with the Walker Quiet-Flow SS Direct-Fit Muffler 21683. This 100% stainless-steel muffler bolts in as a direct-fit replacement for the 2009-2016 GMC Acadia, 2017 GMC Acadia Limited, 2008-2017 Buick Enclave, 2009-2017 Chevrolet Traverse, and 2007-2010 Saturn Outlook, with a 2.5" inlet (ID) and a 2.25" outlet (ID). See the Buyer's Guide tab for the full engine-level application list.

Corrosion-resistant: 100% stainless-steel construction delivers longer life versus aluminized mufflers, and an internal drainage system helps reduce moisture collection.
Easy to install: a direct-fit, bolt-on replacement with OE-style pipe routings, brackets, and hangers — no specialized fabrication or welding required.
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.
Premium acoustic control: OE-style louvered tubes lower noise levels and OE-style domed heads help reduce radiated noise for factory-style sound quality.

Acoustic and flow tested for OE-style sound, and backed by Walker's limited lifetime warranty plus the exclusive 90-Day Safe and Sound Guarantee.
