2001 Ram 2500 V10 Catalytic Converter
Hello all, I need some help here. I am having the hardest time finding a catalytic converter for this truck, or even the correct exhaust system layout for it. All of the layouts show that I Have two ( left and right Sid ) converters. this is not the case for my truck. My truck has one cat, that is two in and one out. with two O2 sensors ( up and down stream ). Does anyone have any info on why mine is different?

California has stricter emissions and if the truck was originally sold for the California market, it likely came with a dual converter setup to help meet CA emissions standards. Sounds like you have a "Federal" truck which meets emissions for the other 49 states.
I'd suggest downloading the 2001 Dodge truck parts manual to see if you can find the OEM part number for your converter and try searching on that.. You can find the factory parts manual downloads here - https://dodgeforum.com/forum/2nd-gen...s-manuals.html

The other oddball on the one V10 I've worked on is the exhaust anchors to the t-case kinda under the driver seat.
People will say they don't know why the NP241D has threaded studs holding the case halves together on the left. It's for exhaust brackets.
Unfortunately, as to the ACTUAL question about the number of cats, I'm no help. Here's a bump for you

The factory parts list shows 2 cats (52103078AH) for federal emissions and one cat (52103201AC) for California emissions. That makes sense because the CA trucks have an additional pair of O2 sensors right before and after the cat to monitor efficiency. The OP truck is likely CA emissions. Walker claims to have a proper replacement:

Curious as to whether or not you're the original owner of the truck and whether or not it was made for the California environment or Federal (legal for the other 49 states)? I ask, as the CA trucks tended to have 4 O2 sensors..

The Walker replacement cat looks like a part number 81512. Lots of places seem to carry it. It has 2 two inch inlets and one 2.5" outlet. It has one port for the upstream O2 sensor. The downstream O2 sensor would require a bung in the pipe behind the converter to accommodate the 2nd O2 sensor. This sounds like it should work for your needs based upon your description.
