It is indeed a stock header from an 04 660. I just took it off my rhino about a month ago because a baffle in the muffler wore out. The head pipe looks to be in great condition. A bit dirty, but I'll try to clean it up and send some pictures tomorrow. Can you use PAYPAL? If so, that would probably work the best. I'll PM you with details and pictures tomorrow when I get it cleaned up and thoroughly inspected.
