Hi all, I have a question about the exhaust headers on my 2001 750ss ie. I've posted this in the Tech section rather than the SS section as I'm not sure which bike the headers I want come from! Reading some posts on "another american ducati forum" :wink: I saw that a guy has had some positive results fitting the headers from a 620ie. These are apparently 40mm dia. compared to the standard 38 (36?) mm. Does anyone on here have any experience/info. on this? I have already gone down the route of fitting free-flowing end cans/pipercross filter/swiss-cheese airbox lid and a power commander with encouraging results, and as there seem to be a few fairly cheap headers on Fleabay I'd like to know which specific model has 40mm headers that would fit on my machine. Thanks in advance for any useful info! Muzzer
