the fxstc already starts off with a lot of customized (chrome) goodies. The only real place I gave attention to real quickly was the pipes. The standard pipes are quiet and boring....not what one expect from Harley. I recently changed the pipes to Vance and Hines Big radius pipes which not only looks great on the fxstc, but sound brilliant.....makes heads and ears turn. The only other suggestion i can make is to choose a nice theme (e.g. scull, flames, etc.) and make small changes like your rear veiw mirrors, foot pegs and even hand grips. This however is not really necessary, but does put your signature on the bike. Enjoy!!
