Any advice? I have a 07 FXDB with stock exhaust. I plan to do a stage one, bit by bit, will fitting the big sucker now alter my bikes performance, if so, a lot ?? or will it be okay for a while??? welcome any comments.

Cheers

probley won't make much of a difference til you open the exhaust up. at that point you're have to decide on a fuel management system in order to add alittle fuel into the picture, at this point you;re appreciate some improvements in performance, have fun

think on down the road. how much modification do you plan on????? if more than a 1kit, spend a few dollars more and put on a stage 2 sucker. it will work great with a stage 1 change out, and ya wont have to spring for another breather if you decide to go bigger than stage one....just a thought!!
