I'm swapping out the V6 for a V8 and I've gotten to the point of making sure the dumb thing can be smogged so I need to know how many catalytic converters there are on the V8 model of a '97 Dakota Sport Extended Cab 4x4 and, additionally, how many O2 sensors there are also. By the way, I live in Southern California. Thank you for any information.

 

you should have 2 pre cats, one off of each manifold and then 1 main cat. one 02 sensor per pre cat, and one before the main. thats what mine is like.

 

A '97 V8 will be the 5.2, not the 4.7, so COULD be a different set-up.

 

well i have the v6 and have that setup

 

I have the 5.2L in my 1998 Dakota, it has a single cat and a pre- and post-cat O2 sensor. Mine is federal emissions, not sure if California emissions requires a pre-cat on each pipe off the manifold?

 

Mine has one cat and one pre cat and one post cat O2 sensor.

 

Before the swap, the V6 had one cat after the Y-pipe with a pre and post O2 sensor. The Edelbrock header/Y-pipe setup i bought for that year with a V8 has the same setup. UWAdventurer, you dont happen to live in California, do you? Thanks for the replies.

 

Mines an 03 5.9 and it has one cat with sensors before and after it....I live in pa though... I'd check ur local regs and go with what they say
