On my 96 SS I blew out a gasket and had to disconnect the y-pipe again to get the header to line back up properly after putting in the new gasket. If you're lucky you can just unbolt it and slide the old one out and new one in but be prepared to loosen everything back up if the header bolts don't go straight back in.
