Engine/Transmission (1994 - 1998) Catalytic converters (don't want it but have to have it)

[ShaneBoone]

My great state of PA wants my father to have a CAT. The exhaust and engine work was previous to this stuff.



my fathers truck--1994 cummins with 4" exhaust with fuel plate #4(i think), a lighter spring for the waste gate, and ATS transmission. What are my options. I guessing my best option is to fab. up a mock CAT for the visual inspection.



I have found 4" CAT's for Diesels, would this cause back pressure that would result in harm to the engine with said mechanical work.



Input or knowledge would be greatly appreciated



my truck---2003 305/555- have not removed the CAT yet.

Unless it was originally equipped with one, I wouldn't think they could mandate having one. This is just me though.

 

[ndurbin]

Some early early 94 2500s (built prior to Jan. 1 1994 I believe) came equipped WITHOUT a CAT (like mine) so unless it didn't orginally have one they can't make you put one on.



But if ya do have to just find an old 4" CAT, gut it out, and install it.

I have one on my 98 but I took it off and broke out the ceramic cone when the truck was new, then reinstalled the can!!!!!!

It's an anti-pollution device, 1994 and above fall under the same rules as gassers. If it was NJ you can be fined for removing your anti-pollution devices. Just like if I put a complete second gen motor in my truck. I am required to put all of the anti-pollution devices with it. If I just do the injection pump swap I'm probably still legal because the its the original block is a 93. The newer injection pump could be argued that it was added to reduce emissions. It would also be illegal to put a 1st gen motor in a 2nd gen truck. Probably illegal to install a non-ic'd motor into a later 1st gen. Not that you would anyway.



If I am not mistaken you are not allowed to remove a working catalytic converter. Thats why on gassers you'll find "Cat-Back" aftermarket exhaust systems. Because that is all the government will allow you to touch.



For those old enough to remember. If I'm not mistaken. When catalytic converters became standard on cars back in 1975/6 Chrysler sidestepped the law because it didn't apply to trucks and vans yet and introduced the Lil Red Express/Warlock and whatever the van was called with the 340 or the 360. We as diesel owners are living in an unusual time in that nobody really checks emissions yet other then opacity testing.



Although, I am totally fascinated by the fact that an early 94 might not be equipped with one. That would be a truck worth having.



Now if I could just get EFI on my truck without the extra set of valves with a p-pump I'd be set... ... I digress.....

If your 94 did not come with one,you don't need one

If It did not come with one from the factory you don't need one. Get your truck Inspected somewhere else. That like seat belts If your car came from the factory without seat belts don't need them. I live In a county that don't have emission test. Greene county. I don't know If any other county does not do emission. If you take off your kitty Isn't It a 10,000 fine?

 

[ndurbin]

Well if someone took my cat out they forgot to take the muffler with it when they did. I did find in a search of emission checks way back when I first discovered it didn't have a CAT that trucks built prior to Jan. 1, 1994 w/ a GVW less than some number (forgot the exact number but less than that of a 3500) weren't required to have a CAT. I don't remember all the specifics of it now but it explained why my truck didn't have a CAT.

Amen



Headshot Zod, Gassers fall under the same category, If it wasn't factory equipped, they can't make you put one on. And you are right baout the cat backs.



My 96 was not equipped, and i'm pretty sure only the California trucks were up until the 98. 5's maybe?



I seriously doubt 94 trucks had them in the north east. Besides that, make them run the truck anyway. I bet it will test below their requirements Several have.

 

[barbwire]

aseigworth, could that beer keg lookin thing have been what they call a resonator? There is something like that on my 99, but I have never had it off to look in it. But someone had told me that it was a resonator. I guess it is a noise reducer . Maybe someone will straighten me out on this mystery

 

[TRCM]

I have a 97 non ca truck, and it is supposed to have one.

 

[DBentley]

where under the hood was that non catalist sticker ? I need one of those stickers.

 

[barbwire]

barbwire, no it was a CAT because it was listed on the window sticker (still attached to the truck) when we pulled the exhaust. Like I said it was confusing to see the straight through design. May have been the 'great pretender' as to keep the Government watchdogs at bay, but hey it's on there it must work! Who was gonna check on them anyway? There is no air pumped into the CAT as there is on gas engine vehicles. My next question is where are they gonna hide the new 4 foot long particulate filter being mandated for '07? This filter is also going to generate 1500-1800 degree exhaust temps. WTF??????????

I may still have the window sticker for mine. I'll have to see what it says

 

[ShaneBoone]

I have the orginal exhaust- I believe it has a CAT

I'll check the date of manufacture, but I still have the orginal exhaust and it has a CAT. I remember he bought it as a left over late in the year. 3/4 ton with snow plow option from a local PA Dealer new.



PA now does a visual inspection for emission equipment. No tail pipe sniffer test yet. The only problem with the old cat- it is 3-1/2" (i think) the new is 4" Stainless Steel. Which will cause restriction for the exhaust.



I'll have to really make sure that is a CAT. Maybe it is something else.

In my area, diesels are exempt from the emissions testing.

 

[Hammer]

radixr ir partly correct,our diesels are exempt from the emissions test which checks for exhaust emissions(soot particulates) BUT,they are not exempt from the eye test in which they are checked to see what equipment that should be there and is not.



IF the truck has any trype of emissions equipment on it(i. e. -cat,resonator,egr equipped motor)then theya re required by PA State Inspection Law to be there. Now,most of our shops usually do not check the trucks with diesels but due to new and much larger fines for them if they do not more and more are beginning to check. Our state is sneaking around with vehicles and dropping in on the inspection mechanics for emissions checks. The vehicles they are using are rigged with defects that will fail them and if they are not checked properly and do not fail or pass(depending on which spy car they bring in)they shops get fined heavily and loose their inspection/emissions liscense.



I know two shops locally here in the York area who now have no emissions or pa inspection liscenses due to failing the sneak testers test. One shop never even hooked the car up and failed immediately and the other was a car which had a aftermarket header/exhaust system on needed a cat and air pump which was removed and got bounced for that.



The shop which did my inspection also failed my truck for graphics on the windows(which is now a failing item in the new laws) and tired beyond the "factory body line" to far(they give you 1/2" beyond the factory body line front or rear). "Factory body line" is defined as the truck with no fender flarers as shipped to the dealership. So I had to install the factory tires and wheels and took it to another shop who passed it with the graphics.



It would certainly be alot more constructive to see them put this much emphasis on removing neighborhood drug dealers as they are making sure we have proper pollution equipment and violation mounted equipment... ... ... Andy

The second gen trucks built prior to Jan 1 1994 didn't have a cat (possible exception would be CA). Mine was built this way (12/93) and has an emission sticker on the driver's side sun visor that states something like "Meets 1993 Fedral Emission Standards".



All second gens built afer 1/1/94 had a cat.

I think it should be against the law for anyone in law enforcement to break the law to catch other people breaking the law. Criminal is criminal, legal or otherwise. After all, what makes them any better if they are driving around in unlawfull vehicles? Kind of a double standard, eh!

 

[biggy238]

It is illegal. . I did know the term, but none the less. They can't break the law in order to catch you.







And after reading some posts... . I'd be in jail for unpaid fines. There is no way state law is going to tell me I can't have tires "past the factory body line" where ole man B. S. is riding around in his ford with a wood flatbed on it because the stocker rotted off.

Just call me Ms. Parks.....

all this and taxes too. just think,we pay for all this bs. america,land of the free.
