Legal?

2006 IH 7400 with a DT466E
Truck was originally titled in California and equipped with California Emissions
You may know that in 2006 CA emissions meant trucks came with a DPF. They had the same emissions in 2006 as the other 49 states got in 2008.
Years later, the truck was sold to a buyer in South Carolina.
Buyer in SC removed the DPF because no emissions is required for trucks built before 2008.

From what I have read, it is illegal to tamper with any federally mandated pollution device.

However, the truck is no longer being operated in CA. Its in SC and it’s a 2006.

Legal?

The filp side of the same coin to ask...

Who in SC is going to interrupt and enforce CA laws?

DPF in CA in 2006 was not a federally mandated device.

A good lawyer will get this taken care of...

I had a '96 GMC pickup truck I ordered new. That night I removed catalytic converter, installed a J.C. Whitney "test pipe". It ran lots better and I got it inspected every year. One mechanic said something about it...then "it must be a Canadian model".

It's not worth it. I ripped off a "Do not remove under penalty of law" tag form a pillow in 1991 and haven't had a good night's sleep since.

"Federally" mandated... not California mandated.

What is the Federal mandate?

As long as it stays in SC I don't see a problem or go back to CA.. as far as other states.. if there was a mandate at that Time which required it if not then seems fine

So when CA mandated their emissions standards before the rest of the country, it was a “CA” standard and nothing to do with FED standards…..
Best to look at door tag and see if it says “Fed. Emissions” or “CA emissions”
If CA emissions then ok to remove DPF

I purchased a backhoe from CA about 15 years ago. Seller was selling it outside of CA because it no longer met CA emissions standards.

This one DOES meet CA emissions but truck is in SC now and had entire system removed.

A lot of this varies from state to state. In my state anything over 20 years old is exempt from emissions check (which is done by plugging into the OBD port, so anything pre-1996 wouldn't have ever been subject to it). However, some inspection stations will still fail you if the check engine light is on.
Not sure if emissions checks are required in all states or not. One would think that since that equipment is federally mandated it would be, but logic doesn't always enter into it.

I would think that any OBDII vehicle would run worse with the cat removed...by this point they were designed to work with it as opposed to the 70s/early-mid 80s when it was sort of tacked on.

Correct. California can not dictate to other states their own rules and vice versa. The feds can dictate to all 50 states.

If you're really worried, look up SC emission standards for 2006. I doubt you will find anything in there about DPF requirements.

There is something similar happening today. CA has outlawed tractor trailers without any type of emission devices on any of their roads. Companies set up shop in NV to send compliant trucks into CA, only for them to switch trucks to continue the trip back east. It's a clown show.

Fed emission standards requiring DPF on diesel trucks started in 2008. The actual standard only goes back 14 years...
