No 02 sensors
Alright guys, i'm a bit confused. From what i understand, i am supposed to have 02 sensors
after the cats on my V10 2500 4X4. Crawled under the truck, can't find sensors before or after the cats. I want to gut my $400 a peice, rattling, p o s cats, but have been told i need a pair
of 02 sims to trick the computer so i don t get the check engine light.
there is no sensor from the manifold all the way back to the muffler. Whats up?

What year is your truck?
96 and up (OBD II) is when they added post cat 02 sensors.
Although trucks 2500 and heaver have different emission standards than passenger cars and light trucks so it is possible your truck may not have any downstream O2 sensors even if it is newer.
