I already have Screaming Eagle slip ons and stock headers with the cat. I also have the screaming eagle programmer loaded. I have a 2014 Electra Glide Ultra Classic. The sound sucks. I removed the baffling material, but put the pipe inserts back into the mufflers and still don't like the sound. I would like to install a set of headers to improve the sound. Is this a doable project and if so, what parts do i need? Just headers and keep my slip ons? Complete set? Will it work with my existing programmer?
