D&D Billet Cat Exhaust Replacement Big Bore Baffle or Muffler for 2017-Newer M8 Harley FLH/FLT Touring Models
The D&D Billet Cat Exhaust replacement Big Bore baffle is a replacement baffle for the D&D Billet Cat 2 into 1 full exhaust system for 2017-Newer M8 Harley FLH/FLT Touring models. This system is one of the top performing exhaust systems available for the Milwaukee 8 engines.
D&D just recently released their Big Bore baffle which has a louder and more raspier tone then their original baffle. Watch our video below to hear the difference. D&D’s Chief Engineer has seen significant increases in mid to high range power on modified engines from stage 4 HD 114 and 117 to aftermarket 120 and up with matching cam and proper tune. 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.
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.
Cycle Solutions Inc. recommends re-tuning your motorcycle if you switch to this baffle.
