The baffle is an all metal perforated 2 1\/2 core ( aka big bore baffle) and will be really loud. Since we are a performance-based company, we always give our recommendations based on getting you the best performance, however if you’re willing to sacrifice some performance, you can go with this loud baffle option for the M8 Billet Cat. We do sell this baffle as a replacement so if you already have the M8 Billet cat you can purchase a replacement baffle. However, removing our baffles can be quite difficult, you might consider purchasing the muffler housing with the baffle. The Billet Cat is an end cap design if you damage the end of the muffler you will not be able to attach the end cap when finished. If you decide to change the baffle, the motorcycle will need to be re-tuned.\u003c\/div\u003e\n\u003chr\u003e\n\u003cdiv\u003e\u003cstrong\u003eNotes:\u003c\/strong\u003e\u003c\/div\u003e\n\u003cul\u003e\n\u003cli\u003eWill NOT fit with the Harley Cool Flow Fan.\u003c\/li\u003e\n\u003cli\u003eBluing and Discoloration are caused by improper tuning and will not be covered under Warranty.\u003c\/li\u003e\n\u003cli\u003eD\u0026amp;D Performance Exhaust Systems are designed for closed course racing applications.\u003c\/li\u003e\n\u003cli\u003eNot for use on pollution controlled vehicles.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cspan\u003eIMPORTANT NOTICE:\u003cbr\u003e\u003c\/span\u003e\u003cspan\u003e*CALIFORNIA CUSTOMERS MUST SIGN AND RETURN THE WAIVER FORM BEFORE WE CAN BUILD AND DELIVER THE EXHAUST SYSTEM*\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e\u003ca href=\"https:\/\/danddexhaust.com\/pdf\/DandD-Emmisions-Waiver.pdf\" target=\"_blank\"\u003e\u003cbutton class=\"button\"\u003e\u003c\/button\u003e\u003c\/a\u003e\u003c\/span\u003e\u003cspan\u003eNEED HELP?
