I do appreciate your comments and I certainly do not assume you know everything LOL! Neither do I!
I do have a copy of the official shop/service manuals for the 1999 Dodge Van. I also consulted with a buddy of mine who works as a team engineer for Indy light teams. He does not know everything either, but is a great resource.
I have been lucky enough or unlucky enough to have a Cat catch on fire on an old Isuzu trooper at one time. So having an exhaust system heat up concerns me. I know mine is heating up right before or at the Cat so I am looking for the reasons its happening!
By the way it sounds like we have similar interests. I started back in the computer industry back in the very early 80's but have other things in my back ground as well.
Thanks,
Jason

So how did your exhaust work out for you. Sorry have been away involved in other projects for a bit. By the way my P505 code that was flagging my IAC circuit turned out the be the PCM. I had it run through the diagnostics at the dealer. The dealer said the PCM was bad. I shipped it with a copy of my previous repair receipt to SIA on thursday, and it was back at my front door this morning when I went to let the dogs out. Bolted it up, plugged it in and connected the battery. Fired up the Van and the check engine light was out, the idle was back down to normal, and the Van seemed to run like a champ all day today.
I will wait a day or so and then take it by the muffler shop to see if the pipes near the cat are still heating up or are back to normal.

Wow, glad it is working now but I am really sorry to hear that! I guess at this point you won't have to worry about the PCM for awhile though.
My van is running great and my gas milage went way up. My combined milage went from 12.5 to 15.5. My city mpg is now 14.5mpg (up from 11.5). I replaced both of my O2 sensors along with the exhaust so I'm sure that helped. I also discovered my passenger floor is no longer hot. It used to get extremely warm under the front passenger seat.
