Description

Quiet your Civic's exhaust and keep gases flowing with the Walker Quiet-Flow SS Exhaust Muffler Assembly 54668. It drops in as a direct-fit replacement for the 2006-2011 Honda Civic, built with a 1.75" inlet (OD) and 2.25" outlet (OD) to route exhaust and reduce noise like the original unit.

Corrosion-resistant stainless steel: a 100% stainless-steel muffler body delivers longer life than aluminized mufflers, and an internal drainage system reduces moisture collection.
Easy to install: a direct-fit bolt-on solution 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 versus straight perforated tubes.

Acoustic and flow tested for OE-style sound, and backed by Walker's limited lifetime warranty and 90-Day Safe and Sound Guarantee. See the Buyer's Guide tab to confirm the application for your vehicle.
