Could anyone assist with the following query please, perhaps someone that has an old exhaust lying around? I am looking for the diameter of the header pipes where they meet the cylinder head i.e. the stubs that are positioned after the flange. A friend of mine is fabricating a 2-1 set of headers for me and requires this info. Thanks in advance.

Have you looked at dominator exhaust for xt660? I have order a 2-1 headers for 800pln "polish money" will get it next week probably

There have been a lot of bad reviews about the Dominator exhaust including people claiming substantial power loss.
