Its 100% stainless-steel construction includes an internal drainage system to reduce moisture collection, though the listed finish is aluminized.

Louvered tubes lower noise, and domed heads reduce radiated noise compared with straight perforated tubes. It includes Walker's limited lifetime warranty and 90-Day Safe and Sound® Guarantee; see Walkerexhaust.com for details.
