My experience is that the EGR system makes little to no difference in the Air Care numbers, at least on the 22R-E.

I like that setup and Baktash seems like a good dude...That said, ever since Hulk had the issue with passing with just one cat, I'm thinking you've got to go with two cats

Well my plan today is get some fuel additive, and try to put another 200 miles on the 80 this weekend with a new air cleaner. Then get some new gas, warm up the truck and see if I can squeak by on the retest.

At some point I'd like to replace the whole mess, and be done with all the dents & rattles down there, possibly get a little HP gain... but in the mean time if I can pass emissions and keep the CEL at bay I'm ok with putting this one off. I'd rather have a new inverter

That is a great setup for normally aspirated trucks! 1 cat is more than sufficient for the sniffer but if the droids at ACC actually look and know how to read the e-info on the sticker under your hood they see that it states (2) 3way cat which means a single will fail a visual. Nothing in the droid manual says the cats have to be the same shape only that both have to be a 3 way so you could use the one in the picture then add a performance type spun high flow after it and still have enough room to go up and over.

My goodness, you ARE starting to look expensive.
That sure looks nice, but I bet it could be built locally for less. The tailpipe looks vulnerable. Is stainless really needed?

You forgot a few things.
1) your forehead
2) your left shoe
3) the cat. No, the furry one.
4) the neighbor's door frame versus yours (leaking heat)

I had a single cat that replaced both of the stock units, installed by AA Performance Muffler. Scott said the newer cats are more efficient and he thought it would take care of everything. The droids at ACC never questioned it, but the actual test results caused me to fail. Had the test results been better, I would have passed with 1 cat, no problem. I replaced the O2 sensors, but this didn't fix the problem. Finally, we put a second cat behind the first, and my test results were excellent.

The last 4 to five times we took a vehicle to the emissions on McIntire and 58th, the checked the number of cats and failed if it was not right. The one on Wadsworth, did not. Go figure.

I am ready to move to someplace without this BS.
