In the front range communities we have to have an active emissions test (not the little one that they do at the gas stations). For cars built after a certain date and newer its a dyno test. I only had to have a tailpipe test because it is titled as a 1965. It has only to meet the standards of a 65. (Which it didn't!) Once the Roush is whipped into submission it ought to be as good as any modern vehicle. Also, they don't check catalytic converters, gas tank pressurization, etc.
These centers are actually a copy of the old Hamilton Test Systems test centers found in Arizona. (I worked for DEC when the Hamilton systems used PDP-11's. Now they're all PCs.) If you are lucky to be in the Denver area you can get a drive by test. They have a mobile test system set up usually on freeway entrances/exits and if you drive by two or three times and pass you get a waiver on your renewal.
New vehicles are exempt for (I think) 4 years. After that it's every two years.
There is some discussion about doing away with it. Almost all new vehicles pass due to the computer controls. Someone even suggested it would be cheaper to buy all those old cars than continuing the tests.
Other parts of Colorado have a much relaxed "gas station" test.
