D&D has just recently released their updated baffle for their Billet Cat Full Exhaust System. This new Big Bore baffle is designed for stage 4 HD 114 and 117 to aftermarket 120 and up engines and has a more raspy, louder sound. 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.
Watch our video as Chris demonstrates the difference on our 2018 CVO Road Glide.
This baffle is sold as a replacement so if you already have the M8 Billet cat you can purchase a replacement baffle. However, removing D&D 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.
