Just wanted to get a word out to everyone who keeps asking this question. I live in TX and we have the same inspections as other green states like CA and NJ. I just had my car inspected at my Mazda dealership and it passed with flying colors even though I have an HKS exhaust which deletes the second cat.

As I've said many many times, as long as you are not throwing and CEL's, you WILL PASS inspection. My car was at Mazda for a warranty repair on my windshield wiper and since my inspection expires this month, I figured I'd let them go ahead and do it just so I could lay to rest people's worries about 2nd cat deletes and inspection.

So there you have it. If you need more proof, I can scan my inspection sheet when I pick up my car. Hahaha. I know there will still be skeptics out there.

so this means I could get a race pipe and its legal? A race pipe only deletes one cat correct?

yes. it's not about the number of cats you remove. it's the fact that there is no 02 sensor on the 2nd cat so there is no code to be thrown if you remove it.

yeah, i had my vehicle at mazda the other day and their chief concern was basically the muffler and decibels put out by the exhaust system. they didn't mention the cat delete in the very least. of course, i'm in canada, but still...

Shoot my probe wouldn't pass no matter what I did to it and I had no CEL or previous codes. Even though I don't have to worry about my vette since it is a classic it will not ever pass exhaust emissions no matter what I do to it and I know some tricks.

But then again those aren't Mazda3's huh.

Either way and that all aside thanks for the info. It puts my mind at ease with my exhuast and inpection coming up...in a while.

did they tell you why it wouldn't pass? if it's not throwing any codes then there is nothing for the machine to not give a passing rating. the only thing left is the human factor so unless there was something not up to spec visibly, then you got hosed.

According to the sniffer the probe was 25 points over something. I don't quite remember since its been about a year but everything was good at idle but at 1500 or what ever the reved it to it failed horribly. That was the probe though so those are notorious for ring issues but still no codes. I was in the same mindset. No codes, no fail. The vette has been tested once just for fun and it failed big time. Just about everything they sniffed for was about 45 points over at idle and the rev. Luckily its a classic so no worries there and the probe is gone so I'm done with failing....exhaust that is.

Oh forgot. Here is Williamson county they not only look at the cel but also do a probe test to search for individual chemicals.

Yea it does. It might have changed though cause I haven't been to the inspection place in about a year and have about another to go since I bought the mazda and its not due till 08. Hopefully they will change it.

where can I get a race pipe? Or should I just have them custom one up while getting my ms exhaust welded?

his probe is pre 98. OBD1. they dont / cant scan those for emission codes. They still get sniffed. Bigger PITA to mod and still stay legal.

actually, 96 and newer vehicles are required to have obd2 for emissions testing. he just happens to live in 1 of 3 counties in texas that still does a sniff test. actually as of this year, only 2 counties still have the sniff test in texas. el paso county just moved to obd only on 1/1/07.

98 is OBDII (2), OBDII started in 96.

I thought the HKS replaces the 2nd cat with a high flow cat. That wouldn't be the same as having a race pipe would it?
