Swoodcock2,
I have installed many Microns and they are the top of the line, as far s I'm concerned. Sometimes, my customers will insist on a Muzzy, Yosh, or some other pipe, and often I get into a serious 'fit' problem. Some headers fit so badly, that you'd think they were made for a different bike. Also the design of the Micron is fundamentally superior to most. For example, most headers just rivets to secure the end caps to the canister wrap. Micron uses a removable end cap to greatly simplify re-packing. The others require drilling out the stainless steel rivets and re-riveting when done. Even the packing is far superior as it's extremely dense and seems to last forever. Performance is also top notch. As with any quality header, you'll pay a little more.
