No, the first catalytic converters installed on GM vehicles was in 1975.
8 years or 80,000 miles which ever comes first
Actually it is not the muffler that contains platinum it is the catalytic converter. The catalytic converter (or "cat" as muffler shops and mechanic's call them) is usually in front of the muffler.
Yes, it is supposed to anyway. it is located under the front part of the cab.
There are two oxygen sensors. One located on the exhaust manifold and one located after the catalytic converter.
On GM, bank one is drivers side of engine, bank 2 is passengers side. Sensor(s) 1 is the upstream sensor, meaning BEFORE catalytic converter. Sensor(s) 2 are located downstream, or AFTER the catalytic converter, therefore, bank 2, sensor 2 is located in the exhaust pipe leading from the passenger side of engine and after the catalytic converter.
Depending what vehicle and year you have, if the cat was failing on a 1996 or newer GM vehicle it would light the "check engine" light.
Catalytic converter efficiency failure, bank two. That would be the passenger side.
The B1 S2 is located in the exhaust system from the drivers side of engine after the catalytic converter.

First off it is illegal to remove the converter. Secondly, your engine will not run properly with the converter removed.---That's not entirely correct. It depends on whether your car is pre-1975, or ALDL, OBDI or OBDII equipped.Prior to about 1975, there were no converters on cars, generally speaking.ALDL and OBDI cars have oxygen (O2) sensors before the converters, and only measure emissions coming out of the exhaust manifolds.OBDII came on line in 1996 (Generally speaking. Some 1994 and later GM models have a modified OBDII.), so if your car was manufactured BEFORE 1996, your car CAN operate properly without catalytic converters. But it shouldn't.OBDII cars cannot (without digging into the electrical system of the engine) operate properly without catalytic converters. OBDII cars have O2 sensors both before and after the converters, and the computer compares the numbers. This is why you have to have the converters on OBDII cars.But, as has been stated, if your car came with a converter, you have to keep a converter on the car.You can buy aftermarket performance converters that will allow you to pass emissions, keep your car legal and are less restrictive than a stock converter, but the performance gains are negligible (1 or 2 hp on average) and the costs are prohibitive.If your converters are functioning properly, keep them where they are. If the converters are clogged or have melted, you'll need to find out WHY and then replace them.
