Passing emissions with TP in CO
My vehicle is orginally from FL and the good ole' state of FL has no vehicle inspections which is great. But i'm planning on moving to FT. Collins and i have just discovered they do vin checks and emissions test if your vehicle is older than 7 years I believe. (I have an 03) so how do you guys pass it while having a test pipe? Do they only check for cel? My evo has been tuned after the tp was put in so it doesn't throw any lights.

vin inspection is only for vehicles are coming from out of state. Once it receives a colorado title, it won't need to be done again. emissions is done one every two years, both O2 sensors and catalytic converter must be present, and the car will be on a dyno for tailpipe emissions.

Fort Collins from what I remember did not require emissions testing, however it could be different now. I know the less populated counties in CO definitely do not require emissions testing. In Denver and surrounding metro areas, if your car is 7 years and older you will need to have an emissions check. They will check under the hood and under the car for a catalytic converter and O2 sensor(s). I believe they will also perform an OBDII inspection. After that they will put it on rollers and perform a sniffer test. When talking to a reputable tuner up there I remember him mentioning that you can get your car tuned on E85 and you will have an easier time passing emissions. Might want to try call some tuners in Denver and see what they have to say.
Also they do have sniffer vans parked on freeway onramps that try to catch emissions offenders.

Vin inspections is for any car that hasn't been previously registered in colorado, it is statewide. Emissions testing is dependent on county you will reside, Ft. Collins requires emissions testing. Vehicles 1-8 model years old are exempt from testing. 8-11 year old vehicle will have a plug in obdII readiness test. 12 years or older (until 1982) will require dyno test for emissions. E85 does not make it easier to pass emissons, their equipment are able to read e85 emissions. From personal experience, just insure a cat is in place and the tune in your vehicle is emissions friendly. Roadside emissions vehicles are not in place to catch offending cars, they are there for what they call "fast pass". If your vehicle passes fast pass requirements, you will not need to take your vehicle in for emissions testing.

The dyno test looks at HC, CO, CO2 and NOx over a period of time in different aspects of driving. If your car runs well in all aspects of driving, then hopefully it should pass. Obviously you will need a cat regardless. Fuel choice could have an affect in how much emissions your car will put out, but it isn't the only solution or problem. E85 can help out but it's not always a guarantee. In my personal experiences, if its relatively stock then you should have no problems passing emissions.

Bolt ons shouldn't be a problem, as long you have a functioning cat and 2 02 sensors is present, it shouldn't be too much trouble. I helped a friend pass his eclipse, he wasn't able to get it to pass. I ended up unhooking the wastegate actuator so it wouldn't boost, and it passed well. p
