I have a 2004 kx250f frame with a 1996 kx500 motor that I purchased. I am wanting to replace the pipe and silecer. I was just wondering what the easiest route for me to take would be? I am not a fabricator, but I do have good welders around. Any help in this matter is appreciated. The pipe is the eve sore on the bike now, and I would love to replace it.
