At my shop I do alot of emission test here in PA(300-400 tests a month)We have the ASM test with dyno(inground model) On my 308 I have classic plates so I dont need to emission test it. PA makes us do a visual inspection so if the cat is missing the car fails. But if you hollow it out and it looks intact, any car should pass if it is maintanied. I havent had time to try my car yet to see if it passes. When I do I am going to test with cats then without and see how the results differ. Also PA is getting the OBDII test for 96 and newer cars someday when the state figures out what they are doing. | ||

Lou - You have to find someone with recessed rollers in the floor. My 328 will not go over an above floor roller either. My 328 passed the last two years with perfect scores. They testing guy was real suprised. You can not pass the Nitro test in Georgia without cats. They also do the visual inspect. I'd like easily removable test pipes so I could swap them myself once a year. This looks like a ••••• on my car. Is anyone swaping them just for the test? | ||

Billy Zissis: How did you back your TR up on the rollers without scraping the front spoiler? Couldn't do it in my 328 in MA (same test) so they allowed a static check. Anyone hear of any car damage resulting from this stupid roller test? | ||

I had already purchased the O2 Sims for the other cat, but when we took it all apart we noticed that my car had only one cat per side. So, since the tubi cat pipes had the brackets for two O2 sensors per side, I installed dummy O2 sensors to cover up the hole. No Check Engine as of yet. Very loud. Ernesto | ||

Be careful playing this game. Catalytic converters are required by federal law, and any tampering can (will) invoke very large fines. (My cars do not have cats  ) That said, unless you're running an OBDII O2 simulator for the second O2, your car should have a check engine light. In most states, OBDII tests are required-- no more sniffing. Basically, if you pass the computer test (no DTC codes, three or more readiness codes on, and pending codes are OK), you go on your way.

Yes, bypassed the cats. I don't live in Harris County, so my cars aren't subject to emissions testing at the moment, but I understand there are 2 types of tests based on the age of the car. I can't remember the cut-off date, but the car will either have the tailpipe sensor test if there is no computer (or the computer isn't compatible with their new system) or the computer is monitored while running on rollers. | ||

I too passed my Testarossa without cats and precats. Over here in NY the test is very stringent. They have a rolling dyno test now. I too thought it would fail but it passed well within the limits. It just goes to show that these engines are very efficient engines. That is how they extract so much power from such small engines. | ||

Tino, my car has no pre-cats. The only cats in the exhaust (one per side) were eliminated. James, how can you disconnect the cats without removing them? You probably mean they they bypassed it with exhaust tubing, but you would still have the emissions problem. Everywhere I've seen, they stick a metal probe in the exhaust tip and test the emissions.

A friend of mine with a Firebird disconnected his cats and passed the Texas emissions testing. For newer cars Texas facilities simply hook up to the computer in the car. He had a chip which fools the computer into outputting the proper emissions codes. And actually, the way the law is written, he did nothing illegal. The law says you must have the cats in the car. They are still there, just not connected! | ||

I don't know what year is yours Ernesto but 2000 and newer 360's have pre-cats. I have noticed after installing my Tubi and looking at other newer 360's that the tips are so clean you would swear you're running lean. I am not surprised your car passed, especially if your pre-cats are still in place. | ||

In CA (and perhaps elsewhere) car must pass a visual inspection, also. And so unless CATs are ordinarily in a concealed location of sorts (covered side-sills, etc.), fair chance you'll get busted going cat-free. That said, I know of a few cars (aside from Ernesto's) that have passed the sniffer catless. | ||

I went to a regular service station. I dont visit my overpriced Ferrari dealer unless I need warranty work. Ernesto | ||

Does PR have slightly different rules that may have let you passed.. Did you go to a Ferrari dealer or a regular emissions service station... | ||

I wish I had photocopied the test results page before I gave it to the DMV office that gives me the inspection sticker in return. I am ignorant regarding the technical aspects of the inspection, but the printout had a list of like five test parameters. Ben, I did not enhance the transaction. For my Supra I have to because it is heavily modified, and I was about to go that same route for the 360 but decided to try out the traditional way first. I really didn't expect it to pass. I can try to find out the local legal limits if you are interested. Ernesto | ||

It's normal if the standard isn't very strict. I bet they don't test NOx. You can squeak through HC/CO w/o cats if the limits are relaxed enough (ie: nowhere near what the manufacturers have to deal with) but not NOx IIRC. | ||

Ernesto - Can you give us some stats? What CO2 and other items are the levels required to pass your inspection and what did the 360 put out? Curious (as I live in CA and have the same thing ahead of me - only with a 12cyl.) -Ben P.S. You didn't enhance the transaction, did you? *wink* | ||

I would be VERY surprised if you were in the UK - this means that your 360 engine is a very efficient clean burning engine indeed. Lucky! | ||

I just took my 360M (or should I say Dino?) to its annual inspection, and it passed with flying colors. This is very interesting because I had expected it to fail as I have removed the catalytic converters. I decided to give it a shot, and it passed! Is this normal? Ernesto |
