Hey inmates! I recently bought a '98 ZX9R that came with a full Muzzy system. I went to dismount the 4-1 Yosh slip on to mount the Muzzy 4-2-1, but I noticed the Muzzy header was missing a piece or two and I wanted to get yer feedback on how to proceed. I wanted to call up Muzzy for replacement parts, but it looks like they went out of business recently. Here are my questions: I seem to be missing this flange piece that adapts the headers onto the bike itself. I do not know what these are called or where/how to get replacements. Is this something that a machine shop would have to fab up? Do I need springs to hold the header pipes to the flanges that bolt to the engine? There are these spring hooks near the connection point to the engine, but I don't see how the connect to the flanges. :wtf Thanks in advanced for your help!
