Bellowed. I've questioned all the others, trying to pinch a penny, but as soon as I can afford it, bellowed it is.
The best is International ceramic coated (riffraff in my sig) and then the non ceramic coated is a little cheaper. Dorman makes the bellowed now for less than 200, but quality has been in question. There are a few threads on it.

I have the ceramic coated uppipes and exhaust housing. Can I tell a difference?? No. Went from leaky uppipes to bellowed pipes and van turbo with stage ones and tunes.
To much change to notice. But keeping thermal forces in the pipes will help with velocity

With leaky up pipes + leaky turbo exhaust housing + leaky turbo compressor housing oring
No tunes i was seeing 1400+ WOT on my pyro.
After bellowed uppies my temps dropped dramatically. Seems like it would hang around 1250 zone WOT. After fresh turbo (Thank you again and again and again Dwayne!) And finding a couple other small boost leaks... with an off the shelf bully bleh tune i cant seem to make it get hotter than 1150.
No ceramic coating on mine.
I think we still have a small boost leak somewhere on Ted's truck to sort out before we can get a fair comparison with his ceramic coated pipes...

The bellowed are better than the stock only for longevity reasons. The ceramic coated are supposed to help hold in heat a bit, which actually helps lower EGTs a little.
Internationals are supposed to be better than Dormans because dormans are said to have some quality issues.
As far as what else to do when tackling the uppies, I'd say reseal the pedestal, add plenum inserts, passenger side fuel line sleeves, and if you ever want to paint the spider and IC pipes, it's a good time for it. Personally I think stock boots are really thin, and I'd go ahead and upgrade to better boots and clamps.

IC boots won't have soot or any other indication of a leak. The whole intake system needs a leak detector to find boost leaks. I did it on mine and found a leak on the intake plenum. That sucked.
The bellowed ups are pliable... they "give" with engine vibration and expansion/contraction that extreme heat variations bring. They just plain make sense.

I didn't think that my up pipes were leaking as bad as they were based on the amount of soot.
Here is a quick video showing how loose my pipes were before I installed the bellowed up pipes:

You do realize to check the exhaust side for boost leaks from the tail pipe forward that you are going to have to remove all the exhaust rocker arms in order to close all of your exhaust valves.

My theory is that if there are leaks like everyone describes (or similar to the video above) then it will be obvious that air is leaking there. If you can't feel or hear air escaping, I'm betting any leaks are negligible.

I'm sure if you have a bad enough exhaust leak you will hear something but if its that bad already I'm sure there will be a visible sign of soot there but in my opinion if you want to truly check the exhaust system you are going to have to close the exhaust valves to isolate the exhaust system. Even on a fresh motor you could have 10% leakage per cylinder on a leak down test. If you have 5 exhaust valves open at one time you will have leakage around all 5 pistons not counting if any of those cylinders have an intake valve open also. I'm curious how this will work out for you but I can't see it helping much but for your sake I hope it does.
