I am bidding on a set right now. I have no reason to expect I would be over bid unless one of you guys does it. 
J/K 
I am also looking at the 3" high flow cats on ebay. They are $38 each. Is this the best deal going? I'm assuming these are the ones sxe60 bought as well.

It may come down to the fact that I don't think any muffler shops will do any welding for you if you don't have cats.
The cats probably come into play in this case. Now if you could just find some 4" inlet and outlet cats and some 4" 304SS pipe to get all that exhaust to the back end (assuming you're running 1 7/8" headers), we'd see something.

<EDIT: the $38 ones are ceramic, the $60 ones are metallic>
I've decided to go with the ceramic ones from performance curve. I'm sure the metallic ones are even higher performance but this is a super low budget long tube project afterall.
Spent ~$125 for the 2 ceramic cats, 4 3" band clamps and 2 2.5" band clamps. Just need the 3" - 2.5" reducers. Once I get it fabbed up I'll probably get it all welded up so the only band clamps are from the collector to the converter ala SXE60.

I got my 3" Thunderbolt cats from Performance-Curve.com. They're still $36.95. For that price, you might as well use them and keep the smell down. I get an ocassional code, but it's easy to clear.
Good idea to weld all the joints aft of the cats. It keeps the system tight and cuts down leaks. Just clamp the cats to the headers with 3" torctite stainless stepped clamps so you can take it apart, if necessary, in the future.

Fed-ex got here about 3pm, man, these things look good. I didn't have one problem putting these in, the ball flanges worked great. I had 3 bolt flanges on my TPIS and hated'em. The ball flanges add a little flexability with the h-pipe. Time to see what these will do with this combo i'm gonna run.

Here's what I got:
- Headers
- 3" high flow cats
- 4 x 3" band clamps
- 2 x 2.5" band clamps
- 2 x 3"-2.5" reducers
- Exhaust manifold gaskets
- AIR tube gaskets
Keep in mind all of this is in the mail still.
But this should allow a weld free version of SXE60's pictures. I plan on getting everything but the collector to cat joint welded soon after mocking everything up but I wanted to be able to band clamp it all first.

Here are my TPIS headers I bought USED at Carlisle for $300. Coated too. Guys, do a little shopping around-there are deals to be had.

You mean you would rather have ill fitting NON coated headers new than coated direct fit headers for the same price?
The first time you start your car after the install-they are now USED.BTW-that was headers only-H/F cats and X-pipe sold seperately.
