Let me start by stating I'm not looking for a smog hookup.

I'm debating on an issue and would like to find out which states has the less stringent emission standards. From my limited knowledge on the subject its looks like AZ is the better place. Do any of you guys have experience on the subject?

Thanks in advance for your responses.

 

Depends not just on state, but locality. There are counties in CA where you only need smog cert when transferring title, and others where you're in for the whole every-two-years multi-stage testing.

Similarly, AZ smog laws from what I've heard and read vary from region to region, with Phoenix and Tucson having the tightest regs.

Google is your friend; all this info is easily available with a few quick searches of each state's DMV websites.

 

reno and las vegas are the only 2 cities in nevada that require smog. registering a car outside one of those localities is smog exempt.

 

It would be Clark county/Las Vegas.

 

CA is whole different issue, to say the least.

You are correct, google comes up with information, but I'm looking for more technical information, which I should have stated in my original and will address in my next post.

Thanks

 

I'm reading up on car emission but at the moment the information on CO's HC's are beyond my capabilities of understanding.

Basically, what I'm looking for is a technical comparison between the test, i.e., is one state's minimum standard higher than another, is the idle test harder to pass than a dyno, etc...

I have attached what I believe are the state standards of the test, if that helps.

Thanks

 

I always thought all states emissions tests had to follow Californias standards seeing that cali started all this.

 

Arizona has a Classic Car program where your vehicle can get emissions exemption. The car has to be 15 years old or older, carry Classic Auto insurance from a carrier like Grundy or Haggerty, and not be your primary driver (i.e., you can't daily drive it to work). Also, your daily driver can NOT be older than the classic car you're trying to insure. There is a limitation on annual mileage allowed, but for most carriers the restriction is between 2500 and 5000 miles per year.

 

nevada also has the classic exemptions in 2 types, classic and classic rod, neither of which need to be smogged after the initial inspection.

clark county standards are about half as strict as california's. all 7's must pass an exhaust sniffer test but the only components you need to pass are what is listed on the underhood label. ie a standalone EMS, high flow cat, 3" and larger exhaust with no precat, upgraded turbo and intercooler, even engine swaps are perfectly fine. you could roll in with a carbed 12A in a 2nd gen, as long as it has EGR, smog pump, cat and passes the tailpipe sniffer it should be good to go.
