I installed the same exact same Fullsac System on my 2012 FLHTCUSE7 this past summer and it is awesome, it is well documented on this Forum all of the benefits of Fullsac and you will be very satisfied !! Steve from Fullsac is a first class guy who helped me with the software install on my laptop one evening well after business hours, Great company !! The answer is YES, everything you need comes with the System, including exhaust gaskets that I went and bought, not realizing the would be included. One more thing, I installed the Fullsac system myself with a little bit of help from a trusted friend, took about 4 hours, but I took my time and made sure not to muck anything up along the way. Oh, you will need a carbide tipped grinding bit and some sort of tool like an air die grinder to grind out the welds on the factory baffles, my advice, buy a good quality carbide bit, well worth it, good luck !!
