Did Dodge ever put on a cat on the exhaust system during the 12 valve years? One of my buddies was telling me they did but I didnt believe him so I thought somebody on here would know for sure.

 

nope. no emissions regulations on the 12 valver..... never have to get an emissions test do ya? (no)

 

Ive never got tested but I hear alot of rumors about emission tests and inspections coming for our diesel trucks in the future. So I am trying to get all the info I can to deal with the system.

 

my truck had a muffler and a resinator on it.

 

they cant do it. if there was no emissions regulations when it was produced they cant later put a regulation on it. if the system thinks about it they will have to find a way around the grandfather clause. you have no worries.

 

I thought they had resonators. I can deal with those but cats suck on a diesel.

 

Yes, the '98 12v had a cat.

 

All 12v (except maybe some early 94) have a cat.

 

I have a catalyst on a 1996 Monaco 32' motorhome with a 5.9L Cummins motor, in my case- it is in the muffler. Go figure.

 

Nope. My 97 never came with one. ALOT of Cali trucks will have them, and I think the 96-98 have EGR too, Cali emissions of course. Most don't have a cat though.

 

Can I give the vin# to a dealer to check to see what exhaust components it had on? Or doesnt that stuff come up on vin#'s

 

Mine is a 96 and It DID!

 

My 98 12v did and it was my understanding all the 12v did?
I don't think any of the VP trucks got them though?

 

I have always had the same understanding. Mine is not a CA truck, and had one.

 

Both my '96s have (3500 *cough* HAD) a cat.
