4.0 mini cats loose and rattling. any experience?

2003 wrangler. they are a ***** to get at. cant really fit a socket or wrench on there. theyre loose and clanking on my tranny and i assume causing worse fuel consumption. any trick to getting to them other than takin manifold out or just cutting. anyone have this issue before?

Not uncommon for those bolts to loosen up. Have to get them from underneath with extensions and a ujoint. IIRC I can get three of mine without the ujoint but need it for the fourth.
Thank you Dave Cole, Dynomax, Falken and all the Spec Class sponsors!!
