Look under the hood on the valve cover or hood and see if it says "CATALYST" or "NON-CATALYST". It shouldn't need or have had a cat origanilly if it says "NON-CATALYST".
If the sticker is gone I'd find out thru a vin check to see if there was a cat installed thru the factory then go from there. Somebody will let you know how to check the vin, can't remember right now. I bought mine new so I know what came on it, I know what I put on it too..ullover:
His computer brought up that early 99's (before 12/98) need a cat. I've done some research and believe he is right. One more thing to bite an early 99 owner in the rear.
I doubt anyone has put a cat on yet but I'm afraid it's going to become mote common in the future for those who had one from the factory. If anyone has a spare one lying around PM me.
E99's had cats....stick and auto. The 01, 02 and 03 275hp six speeds did aswell. However, I did see a 02 275 hp six speed that did not have one installed when it was brand new...It was a mexican built truck, I guess they forgot to install it. LOL

If you can weld or get some one to. Find an old one and gut it and straight tube it. Problem solved.
Everyone can thank the great state of California's majority population for repeatedly voting in the socialist dope smoking, tree huggen, mother earthers :blah: :blah: into office that got you these crazy laws we now have all over the country. These people want use pedaling bicycles and living in grass hunts.

You think it's a :badidea: to want the air as clean as possible?
I have lived in some big cities and made a decision to move to the country just to get away from the air.
AFAIK the smog laws are there to make the vehicles run as clean as they were when new, not to get them to a standard they were not designed to achieve.
Thanks for the link Ron. That is the only option I could find other than finding a used stocker. They actually make a 5" as well. I think two 5" unions and this one ought to do the trick.
I wonder how my truck would be on them test....I have a PMT 1 PCM so there machine might think my truck is a 01 truck correct?? or do they just punch in the vin# ?
That sucks that some states have stupid laws like that. Here in NH anything that has a GVW over 8000lbs doesnt need to pass emissions or even be plugged in. I got mine inspected with my straight 4 to 5in stacks and my 02 came with a cat! Gotta love NH!
I'm all for running cleaner with higher power... Running a smaller cat is going to defeat the purpose of your bigger exhaust. I'd say throw a 5" on it and call it good. No sense gutting something you spent hundreds on, unless it plugs up. Which it shouldn't do.
Almost all cats have a tapered inlet and outlet. You cut the taper off right where 5" pipe will slide right through it slide it up on your pipe and weld it. it will then pass the mirror inspection and your on your way with the same exhaust system you had. Just have to find you an old cat, any of the 94-97 cats will work too.
Do they really actually do anything for a diesel? I understand their use on a gasser and would never remove one. I thought that a diesel that is tuned and in good running condition the only bad byproduct in the exhaust was the soot particles. Does a CC stop soot?
soot and nitrogen so no they dont do much but if THE MAN says its gotta be there......then it atleaset has to look like it..but lord helpya if he looks deeper.
