Looks like these mufflers could use a little relief.
On my last bike (Shadow) I drilled 4 holes aroung center pipe at exhaust end.
Started with 3/8 and opened up til I got sound right. Did have to retune a bit but Oh, what an inprovement.
I'm too shy about doing this on my new baby so how about someone else doing it for me and posting results?

I did that to a Shadow spirit I had yrs ago. Not sure how that will work on out bottom pipe as its not welded around on the outside. I haven't really looked at it that close tho.
