D&D Exhaust Baffle Choices:
This D&D Exhaust system comes with the choice of two different baffles: Vortex Wrapped Baffle or the new Big Bore Baffle:
- The 2 1/2" core Vortex Wrapped Baffle works best on stock displacements up to 114"
- The Big Bore Baffle works best on the bigger displacements on stage 4 114" and up.
D&D's Big Bore Baffle Details:
Our Chief Engineer has seen significant increases in mid to high range power on modified engines from stage 4 HD 114 and 117 to aftermarket 124 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. 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.
