There are 4 of them screewed into the exhaust pipes, there will not be any after the muffler. There are 2 up streams and 2 down streams.
That year has 2 oxygen sensors.
It has 4 of them.

All the O2 sensors on a 99 Chevy Silverado with a 5.3 engine are located in the exhaust. The are positioned on each side of the exhaust manifolds and just after the crossover.
The O2 sensors are located between the exhaust manifolds and the cat converter. They screw in to the head pipes. Those are also called upstream O2 sensors and in some vehicles they are also called air/fuel sensors. There are also downstream O2 sensors that are located after the catalytic converter.

The O2 sensors that are the closest to the engine will be the up stream ones. The ones that are further away from the engine are the down stream sensors.
There are four o2 sensors on a montero sport.

On a 2006 Cadillac DTS, the O2 sensors are located in two main areas: upstream (pre-catalytic converter) and downstream (post-catalytic converter). The upstream O2 sensors are positioned on the exhaust manifold, while the downstream sensors are located on the exhaust pipe after the catalytic converter. Typically, there are a total of four O2 sensors—two for each bank of the engine.
The 2.5 has 2 O2 sensors (both on top of the engine) and the 3.5 has 4 O2 sensors (two on top, and two under the car).
On a 2006 Acura TSX, there are typically two oxygen (O2) sensors. The upstream O2 sensor is located before the catalytic converter, mounted on the exhaust manifold. The downstream O2 sensor is positioned after the catalytic converter, further down the exhaust system. Both sensors play a critical role in monitoring exhaust emissions and fuel efficiency.
