Walker 53521 Other 33.500 Exhaust Muffler sku-159880372

Walker 53521 is a muffler assembly in Exhaust Parts & Emissions Parts, listed with color Other, size 33.500, SKU sku-159880372 and UPC 086387535212. It fits select 1997-2003 Ford Econoline vehicles with an 8-cylinder 5.4 L engine; check vehicle fitment for other applications.

Walker describes 100% stainless-steel construction that resists corrosion and lasts longer than aluminized mufflers, with internal drainage to reduce moisture collection. The listing also specifies an aluminized finish and a combination muffler type. Acoustic and flow testing supports its OE-style sound.

Louvered tubes lower noise, while 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, so specialized fabrication or welding is not required. Walker includes a limited lifetime warranty and a 90-Day Safe and Sound® Guarantee; details are at Walkerexhaust.com.
