I did the hole saw trick a lot "back in the day". It does seem to offer a bit more power, and since Udo Gietl suggested it to me...It's not a lot louder, really, just a little throatier.

I backed away from doing it when an older muffler started to come apart on me. That, and most of the guys who wanted fast bikes had moved on.
