I thought members who drilled holes in a perfectly good expensive exhaust system were crazy. I have to admit I was wrong. Today, based on all the information in this forum, I drilled holes in a perfectly good expensive exhaust system, and the bike sounds better. Since I had a little trouble digging up all the pictures showing what needs to be done, I have attached some of my own. Maybe they'll help others who want to do this modification.
If I had to do it all over again, I'd move the right-side hole up and forward to better match the location of the left-side hole.
