I scored a brand new Alphabet 4 into 1 header for my 550 on Ebay a couple of months ago for a buy it now price of 200.00. Thought I got a pretty good deal. New in the box with hardware and even instructions and warranty card (hardware is only a hanger bracket and some bolts and nuts) I think the fit and quality is very good. As far as pipes rotting out, taking very short rides leaves condensation inside pipes and any pipes will rust out quickly. Also have pods, 650 cam, Dyna 5 ohm coils and 115 mains. Have put about 2000 miles on bike with new header and absolutely no blueing yet.
