I have a 93 Chevy silverado. I had dual exhaust installed. Truck stalls and runs rough now. There is one o2 sensor. I didn't have issues prior to new exhaust.

Yes... The single O2 sensor is only regestering one bank of the engine. That is throwing things off for the computer.

Can I piggyback an o2. Will a equalizer pipe cure this?

It should, but I can't say for sure... Do you have catalytic converters on each side?

Actually, it is federal law that it has converters on both sides. The only option I can recommend is to install converters and an equalizer pipe. Keep in mind, I am only allowed to recommend direct fit parts. Plus, I have to keep it legal.
