There will be 1 before and 1 after each catalytic converter.
catalytic converters are located near the muffler.very difficult to replace
between the moter and tranmision

Legally, yes. Functionally, no.
The catalytic converter should be bolted onto the exhaust pipes. The bolts will have to be soaked in penetrating oil to be able to break them free, then you can replace the converter.
Could be tune up time including air and fuel filters. Could also be a plugged catalytic converter.
The catalytic converter on a 1994 Buick LeSabre can be removed to be replaced. It cannot be removed permanently from the vehicle. Removing the catalytic converter will cause the vehicle to not run properly because there are oxygen sensors attached to it that the car needs. Also, removing the catalytic converter permanently may violate state laws against pollution in some states.
Usually on the "Y" pipe just after the manifold connection points on a duel O2 sensor setup (one on each side) or just before the "y" pipe joins the flex pipe in front of the catalytic converter
if you need to ask to find a torque converter you have no place under the hood. Between the engine and the transmission. Transmission must be removed to access this component.
clogged catalytic converter Agreed.......the smell of rotten eggs is an indication you have a problem with your cataltic converter
The fuse box is located in the glove box on 1991 Buick Century
