6.4 exhaust question

i am looking at buying a 6.4 and i am curious as to what i can do with the exhaust and still pass emissions. i see that people do the DPF delete and take the cat off, but will it pass emissions like that? any info would be great.

It realy depends on where you live and the type of emissions testing that you have in your state. If they inspect the underneath to see if the dpf and cat is there then you will have to put it back on every year to pass inspection then take it off after the inspection. Hope this helps.

Put what state you are in and others in your state may be able to tell you what their expierence has been. Good luck.

Diesels in Missouri don't do emissions testing regardless of the year. If your state does anything more than a safety inspection then you will probably need to be stock to pass it. At emissions tests they usually check to see if you have a cat present at the least and some are much more in depth.

Technically it is illegal in any state...Your owners manual says "it is a federal crime to remove any emissions devices" but in TX they're not too picky at inspection.

I've heard a couple Texans report that they have to do the visual each time. Not sure if it's the same for all of Texas or just their county.

Texas does not have emissions on diesels, they only thing some techs look for under the truck is a muffler.

As previously stated, it is illegal to remove any emissions equipment from a vehicle and use it for anything other than off-road racing purposes.

I think they might test emissions in Saint Louis area. Down here in Springfield/Branson no emissions testing. And, there's some new rule that I can't quote word for word, that if your vehicle is less than 5 years old, you don't need to have an inspection for 5 years. or something like that....

Also note that I have a friend who is a dispatcher for MO Highway Patrol and he does not know of anyone ever being pulled over or cited for emissions equipment violations...

They DO like to dip tanks down here though...
