Cat-Some do, Some don't

[stickk]

I had an '02 PSD that did not have a cat, now I have an '01 and it does. '02 was an auto, the '01 is a std. What's the diff?

[jesilvas]

Well, it might've been a Cali truck.

Well at the dealership if the cat gets plugged there replacement is just a pipe. So the 02 must of had it replaced at one point and time

California trucks came with a cat.

It actually has to do with where it was made. Some assembly plants made trucks with cats, some didn't. You see this in all sorts of things. Some plants used "green" coolant, others ELC. You can identify the assembly plant from the VIN.

[jesilvas]

NEVER seen one with ELC.

Not all of them. Manual transmissions had cats, automatics didn't. I ordered my 2000 with an auto, my buddy ordered his with the stick. He's got the cat, I don't.

Whether it has a cat or not had nothing to do with where it was built. It is all based on if the engine met the emissions standards with the transmission it was mated to.

Yeah, it has more to do with the transmission than year. My 01 6 speed had a cat, same with my buddies 6 speed.

Thanks guys. I just bought an '01 zf6 and am putting on a 4" turbo back exhaust on it and needed to decide on whether or not to put the cat back on the new piping. We have emissions testing here and they will do a visual. Sounds like if all the std tranny's had them then I need to put it back on. I will do what was done to my '06 dodge and gut it, cut the ends off correctly so it will slide over the new piping and tack weld it in place.

Thanks again.
