I took the cats off my car a few months ago, the check engine light came on for about 2 weeks, then shut off and hasn't came back on. I bought the sim eliminators just in case. Did I need to buy them if the light went off? Will the car pass inspection, or do I need to buy some high flow cats?

Thanks!!!!

Where do you live? If they sniff the car and you do a "legit" inspection, the car will NEVER pass without cats...you'll need high flows. But Ive "heard" that "some cars" :rolleyes: never even show up at inspection stations. Damn those rumors.

Texas. They hook your computer up to a machine and it reads everything. Will it know that I do not have cats or will the sim eliminators trick the computer?

The inspection station's computer jsut checks for malfunction codes from the OBDII computer on your car. If you cleared all your codes and you have simms it wont know. Thing is there is no fuckin way youll pass the sniffer test. Time to start letting the benjamins talk.

What year on your Viper?

What simms do you have? If they are APEX, they'll do the trick. I tried Roe's and JH's and they did not work.

As for passing inspection, only the big cities in Texas are doing emissions testing so you can get it inspected w/o the CATS depending on where you are and more imoortantly, where you take it.

You need to get someone to read the code. It will still be stored.

Your car can pass the sniffer with out cats,but only part of the test. If it is running properly it will be clean except for the NOX reading. That is the give-a-way that the cat is bad or not there at all.

A high NOX reading in itself is not a reason to fail, it is the reason that it is high that will fail you. It will alert the inspector to another problem.

If they don't sniff, he doesn't have to worry about it. Period.

I'd be more concerned with the rich A/F condition that he may have. (99's and newer)

I was a little worried but mine passed without any problems. They hooked up to the OBDII and I was gone in 60 seconds /images/graemlins/headbang.gif

I have the O2 sims, no cats, headers.
