emissions test

[drz400smoto]

So I went to set up an emission test here in colorado today and my truck is straight piped and the guy said even if it passes the emissions part it will fail because it dosent have the catalatic converter on it from the factory. So does any one know if there is any way to pass in colorado without factory exhaust?

Did the 01 have a cat from the factory? I know for a fact my 02 didn't, just pulled the exhaust yesterday.

ha, in ohio diesels dont need emissions! and if they did you just bump it up a weight class and you dont again! but i dont believe any 7.3s came with cats...

Wow-even in the inspection happy state of New Jersey light duty diesels (anything under 10,000 lbs GVWR) don't get any sort of emissions check. I'm surprised that a western state would require it-are you sure this guy isn't just talking out his a**? I used to run into that crap all the time in New Jersey. A lot of the drones working the lines were paid $10.00 an hour and couldn't tell a spark plug from a lug nut but they all thought they were ASE master techs. And for the record my truck is an early year '03 7.3L-no kitty from the factory.

So you think I should be able to get by with no cat then?

The main reason Im asking this is because its $70 to get diesels emissions tested here, so I dont want them to pull it into the bay and look and say you factory exhaust is modified so you fail and that will be $70.

There is no way out of it. Emissions is a three part test..
#1 - visual emissions component inspection (All emissions control systems that were originally installed on the vehicle at the time of manufacture MUST be properly connected and working)
#2 - Gas cap pressure test
#3 - the test OBD II , dyno, or two speed idle

Hope this helps you ?

Some 7.3 trucks had a cat and some came from the factory without one. Call a dealership and ask for parts. Give them the Vin# and they can tell you if it came with a cat or not. Get a copy of the build list and take it in with you. They can't fail the truck if it wasn't on there to begin with. Hope this helps.

There is a emissions sticker under the hood. It list all the emission systems that the truck had from the dealer.
