evo exhaust vs 1100s-do they fit?

[buck972]

G Day All
Well after looking at Zero110's awesome mod to his 796 ( fitting a m1100 EVO exhaust headers to a m796 ) this has raised a few questions in my research do the same thing to my M1100s I really would like to confirm these as this is a big cost mod and want to get my facts right first
* is the 796 the same as my 1100 but with smaller cylinders?-I was under the impression this was the case but I could be wrong
* is the m1100 EVO the same as a M1100s ( I know the common differences , I am only interested in the exhaust ) so either exhaust system can be fitted to either bike model?
* Who makes aftermarket headers for these , there dosen't seem to ANY after market FULL systems anywhere on the web
Can anyone answer these questions ?
