Just to let all you guys know and to put this into the archives so people can search later, I found out that the exhaust nuts are 15 mm. However, one of the studs broke off in the middle of me taking it apart, but there appears to be enough thread left to start a new nut on the stud, so I am thinking about leaving it be.... smart idea? I think it will hold and I have heard pressing it out is a PITA..... should I get this done anyways? Nobody seems to have these studs..... but anyways, thanks guys for your help.
