Internal muffler hack how-to!

[j.fro]

1) I was wondering what happened to my formatting. I typed it up in MS Word, then cut and pasted it into the message box. There were a couple of indents for paragraphs, but they disappeared.

2) Mine sounds great. How much material did you remove internally? I cut a pretty substantial amount of material from the pipes. I will admit that it took three tries to get the sound right. On the first try, I was very conservative, just cutting the slits with the Dremel, and it didn't do much. On the third, I cut two sections from each end of the pipe. The sections were about 1.5" each, and now there's more open space than pipe in there.
