Well, I had a friend who knew that i wouldn't pass the visual, smog my car for me. Guess what, It failed the machine test... Uhhhh. He would look past the fact that I had a catted X-pipe on my car, however it failed the computer system. I was under the impression this thing would pass everything in California but the Visual. Am i wrong, or is there something wrong with my car?? My mods are in my sig, not too mention i put back on my stock Maf system just in case. Any help as to why this happened? Thank goodness he did a pre-test, so that Sacramento has no record of me failing anything....
Failed California Smog!!

It was tailpipe. As far as the max readings go.... The max for 15mph is 52. I measured 58. For 25mph the max is 36 i measured 45. I was kinda shocked.. I totally thought the catted x would pass diagnostics. I just changed the oil and beat the crap out of it the way there. Oh well. Just kind of ticks me off. He told me how mustangs have tougher emissions than most cars. I was surprised to learn this.. Im just mad that a 1980 Nissan blowing black smoke will pass with flying colors yet i get the shaft. Oh well. Thats life, guess.

Did you reset the computer prior to heading in? I beleive if the computer was reset soon before a test it will pass a fail code.

I've got Comp 262AH cams and assorted bolt-ons on my 02 GT and failed the sniffer test here in Ontario badly. At 40KPH, the readings were:
HC: 52ppm (limit 52)
CO: 0.01% (limit 0.29)
NO: 70ppm (limit 385)
So far so good, if a squeaker. Then they let it idle down and measure curb idle output:
HC: 772ppm (limit 150)
CO: 0.12% (limit 0.70)
NO: n/a
When I put my factory H back on, the numbers looked like this:
HC: 7ppm (limit 52)
CO: 0.01% (limit 0.29)
NO: 6ppm (limit 385)
and
HC: 7ppm (limit 150)
CO: 0.03% (limit 0.70)
NO: n/a
Put your factory H back on. The cats are superior (in terms of emissions control) to the high-flow stuff.

looks like Im getting the 262s. I had heard you could pass with them but had never seen actual emmissions numbers.

I need a bigger E-Penis.
What high-flow mid-pipe did you have for emissions testing? I'm also from Ontario and I barely passed the emissions test with my MAC catted Prochamber. Hopefully I can pass again in 2009!

MRT catted H. Shortly after it was first installed, I DriveCleaned it and it passed, barely. Since then I'd put the cams in it and put maybe 15,000KMs. If it was marginal new, it's not really surprising it's a fail after a few KMs and a set of mild cams...

Probably not. I'm in Canada and it sounds like we're using similar limits to you (i.e. at 40KPH, about 25MPH, our HC limit is 52ppm, same as yours.) I imagine other states with sniffer inspections will have the same limits.
I'm surprised you were okay on inspection. I thought they'd ding you for that. Up here I've heard of MoE (Ministry of the Environment) cars pulling over a Mustang and the driver being given the gears for having the incorrect mid-pipe on. The one story I heard was that the MoE guy knew that particular year of Mustang came with a 4-cat midpipe and he only saw two on the car. I thought Cali would be even more strict.
We have pretty much the same emission standards here in the Denver area as you describe for Cali and Canada. I have heard that high-flow cats will probably fail the tailpipe test and will surely fail the visual one. The good news is that they are experimenting with a new test that uses a mobile van to measure emissions as you drive by on the highway. I actually passed my last test this way so it eliminates the visual check. On the other hand, if you like to drive around with an off-road pipe without cats and only swap on the real one for annual testing you will probably get caught and recieve a notice in the mail to report to your local emissions check station. In the future the drive-by vans are supposed to replace the other system, and would not "pass" cars but would only flag ones that fail. Of course the guys that own the shops that run the current roller test are fighting hard against any changes.
