You can but the vehicle won't pass emissions.
Yes, if it came from the factory with a converter.
Depending on the exhaust system, there will be one before and one after each catalytic converter
You have 2 O2 sensors on that vehicle. They are both threaded into the exhaust system, one before the catalytic converter and one after the catalytic converter. Bank 1 sensor 1 is the O2 sensor before the catalytic converter.
The catalytic converter is found in the exhaust system between the engine and the muffler.
A 1996 Chevy 1500 4x4 pickup truck typically has two O2 sensors: one located in the exhaust manifold before the catalytic converter (upstream sensor) and another located after the catalytic converter (downstream sensor). The upstream sensor monitors the air-fuel mixture, while the downstream sensor checks the efficiency of the catalytic converter. These sensors are essential for the vehicle's emission control system.
Catalytic converter efficiency failure, bank two. That would be the passenger side.
It did when it came from the factory.
Yes
Yes.
Follow exhaust pipe from engin manifold--should be first thing that looks like a muffler
The catalytic converter(s) would be found in the exhaust system between the engine and the muffler.
