Need to pass quick but my '92 YJ is without a catalytic converter. Anyone know if there's an engine additive that allow me to pass the test until I can get one installed?

You don't NEED a cat to pass air care.
I run an '89 5.0L with no cats, I've passed for four years now. Dude with the mirror keeps tellin me I need cat's, but then I pass without them. A pass is a pass, have them or not. Just need a clean runnin motor.

You have been very ucky then. They are suposed to automatically fail you for not having a cat.

WRONG! '92 and newer, automatic failure for tampering with your emisions system, they can also give you a $500 fine, I cant remember what year it is that the fine goes up to $1000

i've heard if you poke a hole in the bottom of your pipes near the front of the car where its not noticeable it will let oxygen in and turn the CO(carbon monoxyde) into carbon dioxyde and that should be okay, also it drains the water so your muffler doesn't rust out too bad, then after you go through just patch the hole. hope it works not sure if its true or not, good luck.

I should have been more exact with my info. The cat is still on the vehicle but all of the baffling inside the cat is gone so it's now empty. Am I still OK?

If the cat looks like it is in good shape. and your truck runs clean. you won't have a problem. A vehicle doesn't need a cat to pass the emissions part of air care. If you maintain your vehicle well, it will run just as clean with no cat.

I run dual 2 1/4" pipes from manifold to tips, the only mufflers I run are "cherry bombs"(you can see right through them). No cat.s, & no air pump. I change the plugs once a year(before aircare) and make sure your engine is running hot. I kill the electric fan when in the line-up, turn it on around 210/220. Haven't failed yet.
Cat.s suck ass, they filter exhaust by collecting the carbon, then they get clogged, get real hot, and all the collected carbons start burnin-up. thats Y they stink when they are shot(or so I've heard).
If your truck runs smooth I'ld just do it. Then if you do fail, it'll tell you why. Go from there.
Good luck to ya.

Suggestions: run a good combustion chamber cleaner (Chrysler CCC) through (read the directions on the bottle) b4 you go though Airscare. (There is no EGR Valve on your motor to fight the NOx part of the test). Also be sure you rad is full. (NOx is caused by excessive temp in the combustion chamber)Change the oil for sure, and make sure your plugs/filters/ignition system are in good shape.
After this is done take your rig for a good run on the freeway to clean her lungs,
finally put your tire pressure way up (just for the test)(less rolling resistance)
Post your results, you may be OK.
Good Luck

P.S. most overlooked service; Clean your throttle body(with throttle body cleaner)
