Description

Tame exhaust noise and keep your Subaru sounding factory-quiet with the Walker Quiet-Flow SS Exhaust Muffler 21745. It installs as a direct-fit bolt-on replacement for the 2009-2013 Subaru Forester and 2008-2011 Subaru Impreza, featuring a 2.75" outlet (OD) with an offset inlet and offset outlet to match the original routing. See the Buyer's Guide tab for the full engine-level fitment.

100% Stainless-Steel Construction: Heads, shell, bushings, louvered tubes and partitions are built from stainless steel for longer life versus aluminized mufflers, and an internal drainage system helps reduce moisture collection.
Premium Acoustic Control: OE-style louvered tubes lower noise levels while OE-style domed heads help reduce radiated noise for factory-style sound quality.
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.
Easy to Install: Direct-fit design with factory-style hangers, brackets and pipe routings, so no specialized fabrication or welding is required.

Acoustic- and flow-tested for OE-style sound, this muffler is backed by Walker's Limited Lifetime Warranty and 90-Day Safe and Sound Guarantee. Visit Walkerexhaust.com for details.
