Well.... to tell the truth I don't know/can't remember.
I know my 2000 blazer V6 has 2, one in front and one after. to tell the truth that is what I was going by. I will have to craw under my trk to see.

"...
When there is a large amount of oxygen present (lean mixture), the sensor produces a low voltage (less than 0.4 volt). When there is a lesser amount present (rich mixture) it produces a higher voltage (0.6–1.0 volt). The stoichiometric or correct fuel to air ratio will read between 0.4 and 0.6 volt. By monitoring the oxygen content and converting it to electrical voltage, the sensor acts as a rich-lean switch. The PCM signals the power module to trigger the fuel injector and maintains the 14.7:1 air/fuel ratio necessary for proper engine operation and emissions control.
Two or four sensors may be fitted, depending on engine type and emissions package. Sensors are positioned before and after the catalytic converter and may be installed on both sides of the exhaust system. The one before the catalyst measures the exhaust emissions right out of the engine, and sends the signal to the PCM about the state of the mixture as previously discussed. The second sensor reports the difference in the emissions after the exhaust gases have gone through the catalyst. This sensor reports to the PCM the amount of emissions reduction the catalyst is performing.

this is the best I can find for now

use a BFH = Big F**king Hammer
if you are really want to get a ticket for too loud of exhaust,
just take a saw and cut it off.
you might use a block of wood to knock off the muffler.
you might soak the joint of pipe with PB Blaster.
you might heat it up to help get it loose. metal expands when heated.
you might buy a lottery ticket and hit the jackpot.
you might not do any of this and wait till you get the money.
IF IT'S WORTH DOING. IT'S WORTH DOING RIGHT.
