hi, this is the new to me bike

it came with the headers off, one joint on the stock 4 to 1 is broken, and one is cracking, both at the collector joint, I have a mig and was going to weld them but I'd like to line it up on the bike first, is the proper orientation of the exhaust hardware ?

also my muffler doesn't seem to line up with anything to bolt onto, any thoughts?
