Walker 21337 Multicolor Male Muffler sku-167385632

The Walker 21337 Quiet-Flow SS muffler is listed as a Multicolor, Male Exhaust Parts & Emissions Parts item measuring 9.75" x 4.25" (sku-167385632; UPC 086387213370). It fits select 1997-2000 Jeep Wrangler / TJ models with a 6 Cyl 4 L engine; check vehicle fitment for other applications.

Its 100% stainless-steel construction is described as lasting longer than aluminized mufflers, while an internal drainage system reduces moisture collection. The listed finish is Aluminized, and the muffler type is Combination. Acoustic and flow testing checks its OE-style sound. Louvered tubes lower noise, and domed heads reduce radiated noise compared with straight perforated tubes.

It is a direct-fit, bolt-on replacement with OE-style hangers, brackets and pipe routing, requiring no specialized fabrication or welding. Walker includes a limited lifetime warranty and a 90-Day Safe and Sound® Guarantee; details are at Walkerexhaust.com.
