Does anyone know if all 2004 5.9 2500's were equiped with a catalytic converters from the factory?
Thanks

 

My 03 wasnt but if you take your vin into the dealer they can tell you if it was equiped or not. Had to do this to prove to the State Patrol my truck didnt have one...

 

if it's an 04 i'd assume yes, but dodge does throw curveballs occasionally that make no sense

 

Hmmm I saw an 03 just the other day that had a cat. Weird.

 

SO 03's had them HO 03's didnt

 

04.5 when they were on all dodges 03 on so's like red rattler said and some 04s depending on geo that they got sent to

 

what was the difference between the SO's and HO's? Im assuming the SO's came with either an auto or an NV4500 and the HO's came with an NV5600? Im pretty sure this guy has a 6 speed with a cat, but I'll double check next time I go back home, I could be wrong and thinking of another truck

 

Thanks guy's, I'll check with the dealer Monday and give them my Vin., we'll see what they say.

 

Out of curiosity why are you needing to know? Emissions testing? Not one of my strong areas since I live in OK

 

As of 2010, California passed a new law that all diesel pick-ups 1998 and newer have to be smogged. 50% last year and the remaining 50% this year and so on from here on out. I'll have to have mine smogged starting this year. I've been told one aspect of the test is visual, ie all the emission eq. it came with from the factory must still be there. I purchased my truck used, out of state 4 years ago and it does not have a cat. If it came with one, I'll have to put one back on.
Thanks
