Does any body know how much power I will gain if I cut the cats out of the head pipe on a 2010 Ultra Classic? Some mechs say not much other say it will help a lot. I know it will help make it run cooler. Just trying to justify the cost, is it worth it? Get headers or just cut the cats out? I have slip on reinharts mufflers and the air cleaner mods with the down load.
