I got the direct fit Walker cats a few years back figuring I would eventually need them. I ended up installing them along with an engine in The Ice Car less than a year after I bought them.
They are indeed the 2 cat deals, which frees up a bit of room down there.
I didn't hook up the thermactor stuff either. Install was 2 or 3 summers ago, no issues that I know of although I'm sure they aren't as efficient without that hooked up and a little smell some time to time.
Also, if you need the exhaust manifold flange studs I recommend Dorman 03135 (Thread Size #1 7/16-14, Thread Size #2 7/16-14)
I used Dorman 03099, but think 03135 would have been a better choice.
Dorman 03129 are NOT correct (M12-1.75).
If you find something other than Dorman, you need 7/16-14 thread for the manifold side.
