I did consider registering there, but I guess Missouri requires the emissions system to be checked when transferring an out of state vehicle in, so I figure I'm screwed either way.

I wonder if the truck would run okay, without throwing a check engine light, if I just installed the CAT and DPF and ran to emissions really fast, then remove it until I move and have to go through the Missouri inspection. Emissions is only 5 minutes from my house.

Any thoughts?

Cat won’t cause a problem, in fact you wouldn’t notice any power, egt, boost differences with or without the cat.
What you will notice is the exhaust isn’t as stinky, that’s the emissions part with no sensors.
As far as the DPF being put back on and still tuned

Thanks for the quick reply. I suppose it's only a few hours work. If it's not raining in the morning I'll throw the parts on and make the trip to emissions and let everyone know.

Hopefully you have a scanner to clear codes if needed, it wonít pass if you have any trouble codes.
What part of Phx are you located ?

I'm in Mesa, AZ.

The results are in and the truck passed emissions, .07 opacity. The loss of performance sure was noticeable and it didn't throw any check engine lights, so I guess I'm good until I move.

Thank you everyone,

Denny

Missouri only requires a safety inspection if you are outside the greater STL area. You can Google what counties around the STL area require emissions. The safety check will look to see if the EGR and cat are in place. The inspections makes no mention of the DPF. FYI, Dean

Good to hear you gotsíer passed.
Just keep the parts incase you ever need to put it back to stock for emissions law changes or selling it.

Curious did you connect all sensors on the DPF and leave your delete tune in ?
