Colorado emissions changes?

That's the thing that really gets me. Just put an analyzer in the tail pipe. If it's cleaner than it's supposed to be, why does all the other stuff matter?

Cause Volkswagen.... If you are savy enough to put and 8.1 muti port dis engine in a 35 year old car, you can tune it to pass any test. Then once passed tune to your hearts content.

But that could happen regardless. I mean tuning for the test and then changing it for day to day driving.

Exactly. There's nothing to stop a person from removing the cat and all the smog parts after the test is passed, then putting them back on prior to the next test.

That's just more work than the typical person wants to do.
 
Of course there may or may not be a "test cat" pipe in circulation between some Subaru enthusiast friends of mine they swap on before their test and swap out when they get home.
But they are far from the typical person.

Hypothetically.
 
More work than I wanted to keep doing. So I registered mine in a non testing AZ county.
Added bonus $126 for 5 yr tags.
Kommiefornia $186 a year.
 
In CA you need to have all the emissions equipment that originally came with the vehicle for anything after ‘75. So if they’re going to adopt the CA laws then you’d be required to put the cats back on to pass the visual and sniffer.
I believe that's the same for CO now too. It was a 25(?) year moving window, now fixed at 1975. I might be getting that mixed up with the collector tag stuff.


A little clarification here. Having a little caffeine clears the mind some I guess.


The coming adoption of california emissions standards is particular to the zero emissions segment. This will come into place for the 2023 model year. Manufacturers will be required to sell more zero emissions vehicles. 4.9% in '23 and up to 6.1% by '30.

This was adopted this year but has no bearing on existing vehicles. Meaning those of us non-cat equipped scofflaws are in the clear for now.

I have not found any news report to indicate of coming legislation to tighter regs on older vehicles.
BUT...they may make it difficult or impossible to register older vehicles as CO has done with the military vehicles. Just a thought...
 
Here's the current info on collector plates straight from the Colorado.org DMV site:

About: Vehicles must be
  • (a) Model year 1975 or earlier;
  • or(b) Model year 1976 or later that was registered as a collector's item prior to September 1, 2009; except that a vehicle so registered is not eligible for registration as a collector's item upon sale or transfer to a new owner;
  • OR (c) A model year at least thirty-two years old unless the vehicle was registered before September 1,2009, and meets the requirements of paragraph (b) of this subsection (2). if the vehicle is being registered under this paragraph (c) and in the program area, as defined in section 42-4-304:
    • (i) The vehicle must have passed an emissions test meeting the standards of part 3 of article 4 of this title within the last twelve months before being initially registered by the owner as a collector's item;
    • and (ii) The owner must sign an affidavit DR 2839 that the vehicle will not be driven on roadways for more than four thousand five hundred miles per year. All taxes and fees shall be five times the annual taxes and fees normally assessed.

Available For: Passenger cars and trucks that do not exceed sixteen thousand pounds empty weight. Misc. Info: Motor vehicles that were grandfathered in prior to September 1, 2009 may remain registered as a collector's item until registration is allowed to expire or upon sale or transfer of ownership.​

So my plan is to get the collector plates next year when the crew cab will 32 years old and then I will have 5 years for sure. By the time 5 years is done I'll likely be ready for a new project.
 
I've been chatting with my local exhaust shop. He has not been able to get any solid info on what or what isn't happening on Jan 1st. I have been registering anything I can with collector or horseless carriage plates. The horseless carriage plates are for vehicles over 50 year old. Only 1 plate and $16 for 5 years. I've also kept some of my vintage cars titled in Michigan's vintage plate program. $35 for life and you get to use the year of manufacture license plate.

Both my '77 and '79 have collector plates. I think it's funny that the '77 without a cat. gets much better emission readings than the '79 with a cat.

I should look at horseless carriage for the 66. I didn't realize it's old enough.
 
Not sure on CO as I haven’t lived there for years. In CA every aspect of the engine has to be stock or CARB Approved for anything 76 or newer.

There are some exceptions. Anything registered as a diesel is exempt up to 1997. There are also three county tier levels most are the strictest tier—must pass visual, sniffer or obdII if so equipped and no CEL may be on or stored.

The middle tier is for somewhat rural zip codes, it’s sniffer or obdII. So for older vehicles, if it can pass the sniffer, you’re good to go.

The best tier, which my zip happens to be in—the vehicle is only required to be smogged on change of ownership, but never after. Just annual registration fees.

That’s what I’m gonna do - switch all my vehicle registrations to my cabin in Humboldt which is a change of ownership county. :woot:
