That's a "bitch of a job" for either side. For a big car....there's not a lot of room in there. I dropped my engine in with the manifolds off, so that I didn't scratch any paint...I regretted that decision. Each bolt will be it's own problem, have a full array of tool options at your disposal for this.
I actually made a set of extended nuts, that come neatly out to the front of the manifolds. This won't help you get the bolts out, but will make it go back together a lot easier and looks nice.
Some people have suggest no-gasket, I put them in anyway.
As far as the "tips" go: I'm going to add them to mine as well. The stock pipes ( what I put on) have a funky turn downward at the end and come short of the end of the bumper. I like the rectangular Mopar tips and will be looking for a set at Carlisle next month, as well as parts for my new project, a 62 Dodge D100 Utiline
