After seeing so many positive replies to this mod, I decided to try myself on my 2000. I ended up with two 1/2" holes in each pipe. One hole, not very deep, angled inward, and a second hole, deeper in each pipe, also angled somewhat inward. I think there's room for one more hole, even deeper. But I like it the way it is. Between de-snorkeling, installing a K&N element in the stock box, and the muffler mod, I get pleasing sound all through the RPM range. I'm surprised the pipes don't make any more noise than they do at mid to high RPM. Mostly a real deep tone, just off idle. Very nice!
