DPF Delete and Emmissions Test

[lmbass2006]

I am looking to do some performance upgrades to my truck and have seen pretty much everyone say to do a DPF delete exhaust. I live in TX right now but will probably be moving up to CO in a few years. Will the truck pass emmissions tests with the DPF delete on it or would I have to put the stock exhaust back on for the test?

back to stock with a stock program. Lots and lots of information on this subject in numerous existing threads. Good reading to help you make the right decision.

I live in texas also an have never had an emmission test on mine and i have had my truck for to years now and been twice to the inspection sticker...

I know they don't test them here but the they do in CO which is where I will probably be in a few years and plan to still have my truck.

You dont have to have your truck emissions tested for the first 4 years from the original purchase date here in CO and then its every other year after that, this is for 07 and newer vehicles only I believe

If you have to get emissions test done, put the DPF back on the truck and tune it back to stock. That is the only way you would pass.

If Colorado requires testing based on the new rules the EPA have put out, then no, you will not pass without the DPF in place. One of the tests is an inspection to verify all emissions equipment is in place and working.

It also depends what part of Colorado you are planning on moving to. Anything on the eastern slope - yes; western slope - no (for now).

I really appreciate all of the information. Sounds like unless I want the headache of changing everything in and out for the test, I should look to do all I can with the DPF in place. Thanks.

Putting the dpf back on once a year is no big deal, it takes about an hour to do it start to finish at the most once you figure it out.
