i think i saw that bike in tx for about 30k. the previous SE fatboy was 29,900.
errasa, it won't be cheap. i'd start with a stage II and new pipes. if you're gonna suck in more air, you gotta let more get out! i'm told that rhinehart pipes are about the best you're gonna find for performance, but they're not cheap. harley will tell you to use their screamin' eagle pipes with the "power chamber." basically, it's a 2 into 1 that looks like a 2 into 2. i've been told by harley folks that it was designed by harley but made by V&H. i know that V&H has a similar version of the pipes, but i don't know if they make the one with the screamin' eagle name. anyway, it's going to be expensive no matter what you do. that's why my fatboy is still slow!
