Both brands have a good reputation, I had a walker muffler, but the cat I got was
just the cheapest I could find, most don't last more than a few years according to
the smog tech I talked to.

OEM Cats are the best, designed to last like 50K Miles to meet the Federal smog
warranty required on all new vehicles

This is what I put on my '92 and it works just fine. If you poke around on ebay you can find cheaper ones.

You can also get 5' of SS pipe for the same price.

only two problems are, that stainless pipe in place of converter=SMOG FAIL,  and also gets you in trouble since I believe the cat is a federally mandated component.   

I'm simply doing a high flow, because as much as I dislike the converter, it needs to be there by law.

Questions for you on that converter Bill S:
1: does your egr still function correctly, ie no code 51 or p0400?
2: how did you address the rear o2 sensor bank? Or does the 92 not use one?

The 92 doesn't have one.  :)

That being said, I recommend running a cat on anything other then a trail rig.  It really is better for the environment, even if it is a pain in the ass.
