Have 07 Road King Classic and wanting to put pipes on. Looking at either Pythons or Monster Ovals. Went to the dealer and heard the Pythons on a Police bike and sounds good and have a fellow Navy Chief that put the Pythons on and sounds really good but have not heard the Monster Ovals yet and really want to make the best choice, also heard that if I put the Ovals on I have to put a fuel pak and a free flow air breather on as well, is this true? Plus the Ovals are about 200 and some change more!! Any one have either or and would like to hear what others think.
