562xp muffler mod!

[thumbilly]

I don't want to beat a dead horse but I know I've seen threads on here about this with some really good info and pics. I can't seem to find them and I'm really beginning to want to do a mm on my 562xp and 555. Any info or advice would be greatly appreciated.

Remove muffler, grind everything on the inside out and enlarge factory exit hole.
