What the legality around removing catalytic converters on diesel trucks? My cummins dodge didn't have one, my 06 LBZ does.

Anyone know? Does it go by the state?

sorry, put this in the wrong place, let me move it over to the exhaust section.

get rid of it. even though it is not legal. i removed mine but kept the entire system if needed. be ready for P0401 codes though. not anything to worry about but a pain in the a$$. PPE makes a module to trick the pcm though.

Don't know what state you live but here in Pa there is no emmisions testing, kill the cat:

Well, its straightend out now

In the future if you post in the wrong forum its probably best/easiest to either click on the "report a post"(the little exclamation piont) or send a PM to a mod that you see online. We can move the whole thing for ya

It is illegal. But what the man dosent know Keep your cat in your garage though in case you have to do emmision inspections ect.

I got no light in the dash(duno if there are any soft codeds) and I have 300 miles or so on my truck with no cat and just the front pipe(no muffler or tail, all I have is what most manufacturers incorrectly call the downpipe) Your results may varry though.

mine did not trip a light until 6500 miles. now it happens about every 600 miles or so. just swing into autozone and have them clear it. My buddy is designing a scan tool that is the BOMB!!!! will be getting one of those. he won tool of the year at SEMA 2 years in a row with his scope/diagnostic machine.

Where I am, it's not really a problem until you have to get the vehicle inspected. When theat comes around, you just bolt the cat back on.

Regardless of emmisions testing in your state or not. It is illegal to remove a catalytic converter and not replace it (if originally equipped), Same with tampering/gutting. I believe it is a federal environmental law.

I was once told by a Wisconsin State Trooper that anything that is altered from the factory specs is illegal - technically speaking - of course.

Jersey does do emmisions testing. Unknown for diesels. I still havent gotten an answer yet if I have to get smogged here or not. No one seems to know. I guess I'll find out next month.

 

[mikes280]

when did the feds make it a law that all diesels have to have a cat

I dont think there is one, unless it comes with the upcoming improved emmisions regulation. However, if your vehicle came equipped with one, I believe it is illegal to remove or tamper with (without replacement).
