Walker 21054 Multicolor Exhaust Muffler | sku-106270087

Walker Quiet-Flow SS 21054 is a Multicolor combination muffler, size 9.75" x 4.25", listed under Exhaust Parts & Emissions Parts. It has 100% stainless-steel construction, an internal drainage system to reduce moisture collection, and an additional finish listed as aluminized. The source describes it as a broad-market muffler with longer life than aluminized mufflers.

Acoustic and flow testing validates its OE-style sound. Louvered tubes lower noise, while domed heads reduce radiated noise compared with straight perforated tubes. This direct-fit, bolt-on replacement has OE-style hangers, brackets and pipe routing and requires no specialized fabrication or welding.
