I know in NJ they do a visual inspection for the cats along with checking the emission for errors via plugging into the OBD of the car. If your state doesn't do the visual but checks the emission via the OBD port, a tuner can possible get the car to look OK when scanned. If they probe the exhaust, your not going to pass.

The smell will most likely tip the tech off without him even having to do a visual.

Then you be in the system as failing and will need to have the visual and well as the scan done.

That how it will go down in California.

Colorodo? I would check with your dmv in Colorado to see what the exhaust system/emission laws are, but it is a federal law that any part of a working emission control system cannot be altered or removed, that being said, some states are more lenient than others

I pass emissions all the time especially after a few beers, but my wife makes me go out to the garage.

OP - You will need to check the requirements in CO. Here in Texas, they dont do a visual and only do a ODBII test. With a little tweaking, you will pass emissions here.

for Colorado:
  • New vehicles are exempt from inspection for the first seven model years.
    • A 2011 vehicle, for example, doesn't need an inspection until 2018.
  • Vehicles 8 through 11 years old will be inspected using onboard diagnostics (OBD).
Vehicles manufactured beginning in 1982 that are at least 12 years old will be inspected using the “I/M 240” dynamometer (treadmill) test.
