OE-style louvered tubes reduce 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, requiring no specialized fabrication or welding. The finish is Natural, and the muffler type is Combination. It comes with Walker's limited lifetime warranty and 90-Day Safe and Sound® Guarantee; Walkerexhaust.com has the details.
