[Z06] Catch can & smog
More knowledgable smog guys know better and your stuck, but the smog shops that crank cars through at top speed seem to let that stuff slide the most. If it passes at the pipe and nothing is blatantly visible as being aftermarket or disconnected they just slide it through.
So it totally comes down to your smog guy since any car will pass at the pipe with the cat installed. Any tune that's good enough to be driveable is good enough to pass at the pipe so that's a non issue. Just a matter of finding a busy smog guy who just wants it done and gone and on to the next car.
Of course in a perfect world they would just go by what comes out of the pipe since that's the whole purpose of the test, but when the govt gets involved they like to make lots of jobs for their friends and lots more rules they can fine you for to make more money so of course it's kind of out of control.
Sadly here in CA they are trying to break from the Fed govt standards so they can screw with people even more. To the point of sueing the EPA. What fun these people are. And of course it's for our own good because we can't be allowed to decide things for ourselves. Lucky we have our betters looking out for us. I wish I could buy pollution credits like they let the big companies do instead of meeting their emissions standards. Say $150 bucks a year and I can do anything I want to my car as long as it passes emissions at the pipe. What a dream.
I have to agree with you on CARB, and the EPA as well. The CARB was established in 1967, remember it well as life in California would never be the same. Granted at that time we in the SF Bay area were having a lot of smog days, days where everything was brown and it some times got bad enough to sting the eyes and made breathing hard. The smog alter days were when folks were advised to saty indoors. But,...... don't ya just love when theres a BUT coming , But after BILLIONS and BIllions of tax dollars and twenty years , the air was 99% of clean (pre 1920 standard). No more smog alter days for years now ,even in the stale air of LA.
But the CARB wants that 1%. 1% at any cost. There is such a thing as cost effectiveness. That is when something can be attained at a reasonable cost. Billions of dollars for 99% fresh air? Cost effective , but billions more for 1%? is power mad and controling. Eleven people make up the board.
Shoot the EPA , I remember when the EPA was announced . It was to monitor ......thats right MONITOR the air and water , ect then make reports to 15 different FED depts. Then in 1970 , the EPA absorbed 15 agencies with a mandate to protect American air and soil from Americans. EPA now has 17,000 strong with 12 labs. Their mandate has changed over the years , they now enforce the laws that they write.
Other than the IRS, the EPA leads the list in FED agencies that Americans fea( NYTimes 1991).
Here is a view of my car from the bottom.



And the CCA Catch can...


If the exhaust is clean than it should not make a difference what one has bolted onto their engine. I agree it is just CA screwing us over.
