need your help guys

tore my xj apart today to fix an exhaust leak only to find a manifold that someone tried to repair;;;;bd weld with holes in it.well it looks like header time.been checking around and found a pacesetter and a hedman what i need to know is do these come with egr and o2 fittings if not what do you do.can you do away with them or what.my xj is an 1989 with auto trans.it seems like alot of the header makers start with the year 91 whats up with that.appreciate any help you can give me.

Go to a junk yard and get a header from a newer model xj.

'91 is when the HO engine came out, but I'm not sure what that has to do with header availability.
