New H-D Performance Coming Soon
December 14, 2007
In addition to pipes, D&D will be releasing their ThunderMax Electronic Fuel Injection (EFI) Controller and AutoTune Module. This combination offers performance gains through a free-flowing exhaust while the controller/ module setup improves throttle response, fuel economy and more efficiently controls heat.

The D&D/Zipper’s performance package is ready to be shipped to dealers and should be appearing on shelves in the days to come. Head over to www.danddexhaust.com for more information.
