I am planning on running duals on the freewheeler and doing away with the cat, that bad boy gets HOT!! I know a few people that have put these on their ultra's and say they are much cooler and a decent performance gain. I was just wondering if anyone here has put them on the freewheeler and if you ran into any fitment issues or if it all went as planned. I have noticed that a lot of stuff, even from Harley, that is supposed to fit don't. Just trying to find out before I spend roughly $600 on head pipes. http://www.rushracingproducts.com/headpipes.html
