Note: This is for a 5th gen. Everything here is MY observation, on my bike, and I have not elided those bits where things didn't go smoothly simply to try and be helpful. Your experience may be different. Your bike may be different. Your headers may be somehow different.  Deal with it yourself.     OK, I got started on my installation after work today. So far I have removed the old (Delkovic) headers and gotten some things cleaned up. I ran out of light, so I'll put them together
