eMission: Fail (now pass- woohoo!)
Emissions time. Already got my extension which runs out next week.
Went to my dad's to reinstall my cat. Find out he recycled my cat for $20.
Pulled a cat off a stock 1.6 miata that was at the shop. Tried my damndest to make it fit. No chance.
Found a junk cat of unknown origin, removed the heatshield, and installed it around my test pipe. Convincing! Looked just like a cat. So I went to the testing station.
Results:
Reading Allowed
25/25
HC 143 160 pass
CO% .76 .90 pass
NOx 752 1179 pass
50/15
HC 149 166 pass
CO% 1.86 .93 FAIL
NOx 828 1304 pass
The tester says to me, "I think you need a new o2 sensor."
So I'll have to buy and install a cat.

This looks like a winner to me:

Can I MIG steel flanges to stainless?

I dunno, MS says to lean the fuel in the manual here:

But you're double the limit so I don't know if that would help enough to pass

94106 is a good cat. In fact, I believe that is the exact same one that I've got on my car (from Tony).

cool, thanks Joe. I saw some other generic 2.5" cats, but this one was an actual name brand. I submitted an offer of $52 shipped, and the seller accepted.
glad that MIG will work. the other welds in my exhaust are ugly as sin, so it will be right at home.

Looks like requirements over here are a little bit more strict, here are the maximums that are listed on my last test for the '90:
15mph: HC=134ppm, CO=0.82%, NO=847ppm
25mph:HC=108ppm, CO=0.71%, NO=786ppm
last test was stock with 240k on the old engine and passed really well on CO, but had high NO. Next month im testing w/ new 3"cat, rebuilt motor, and megasquirt should be no problem.

Could you post a picture of your pseudo cat? I live in a location that only requires I have a cat in place, no test what so ever. I ran a test pipe, but got nailed and had to install a new cat to pass. I thought about gutting my present cat, but could not bring my self to destroying a brand new part. Camouflaging a “test pipe” sounds like a winner to me.

My dad's welder uses the 'big' spools, at $60 a pop.
I will have to find a kind volunteer with a welder, or pay a muffler shop or something.
Uhm, what if I get SS flanges? Can I MIG SS to SS? They're the same price as mild flanges, it looks like.
