so I have a 98 dakota sport with the 5.2 and 8 speed, I;m doing JBA headers and i want to do 2.5" true duals with highflow cats and x pipe and magnaflow mufflers and exhaust pipes, my question is what to do with the O2 (oxigen sensors. Do I need to convert to a 2 upstream deal or do they sell like a pig tail adapter harness to run the true duals or one oxigen sensor be good for both banls?

 

.If you have the x-pipe right behind the headers, put the front O2 sensor there, rear just goes behind one of the cats. Doesn't matter which one.
