ok so i started the debaffling on my C50..... I was not able to find a way to use 2 hole saws at once so i decided to do them one at a time. I was able to cut the first hole on each muffler with the 1 1/2 inch hole saw with no problems at all. Cut them both in under five minutes total! Then i changed to the 3 inch saw and started to cut and... uh-oh.... this damn thing wants to go all over the place.

I cant seem to be able to hold it center. Am I missing something?? what am i doing wrong?? I am guessing that is why it should be done with both saws at once so the saw on the inside can keep it somewhat centered?... or is this where this arbor thing comes into play??
Can someone who has debaffled please give me some advice.... I would really appreciate it
Oh i almost forgot... I turned my bike on after cutting the first holes on each muffler and i can already hear a big difference. I like what I hear so far!!!
