I have a 2012 Ultra Limited (FLHTK). I love the bike but it does run hot. I ride in either NH or AZ and when in AZ it can get really hot. Was at the Harley dealer this week and one of the mechanics will cut the cat out of the pipe and re-weld it as it if was new. They tell me I do not have to do anything else - I can run stock air filter and pipes and not worry about reprogramming - the bike will run cooler and with a little more power and a little better mileage. Cost = $250. Am I getting the straight skinny on this? The stock system will be fine without the cat? Anyone had problems from removing the cat? I need to decide in the next week. Thanks to anyone who can comment.
