I have a question similar in nature to Molokaimike, but a little different... didn't want to hijack his post.
On my 2017 TG, I have already changed my AC to a DK Outlaw 606, with External Breather System, and still running the stock headpipe and HD slipons. I have always wanted just a bit more rumble, but not screamin' ass loud, and I didn't want to remortgage the house for what they are getting for a lot of the aftermarket pipes. One suggestion was to remove the stock baffles and install DK Thunder Torque inserts... bought the inserts, but never did the baffle removal, as I was worried that it would be louder than I liked, but then I would be stuck having to buy new slipons anyway. A friend suggested looking at Fullsac Performance; they have a High Flow Baffle kit for stock Touring HD mufflers. This looks like it may just be the ticket, if they are louder than I like (Fullsac claims "slightly more rumble" and increased performance), I can add the Thunder Torque inserts (I may do that anyway for a low-mid bump). Jack, you seem to be a fan of the TT inserts, and I know from personal experience with my 2014 TG, I was pleased with the low mid when I installed 4" Rush slipons and Thunder Torque, and when I ran into the guy who bought it when I traded, he complained about the low end; I saw that he had removed the TT's to make it louder. I already have the bike tuned with a PowerVision, but I am thinking that with the stock headpipe I shouldn't need a change there.
Any thoughts?
