Good morning,

When they get clogged, the engine cannot send exhaust to the tail pipe. The engine cannot breathe correctly and will cause driving issues. The engine will only rev up to a small RPM and the car will have no power.

A total of 3. One for the left bank, one for the right bank and a warm up converter.

I attached the parts list for from Rock auto. It shows all 3 converters.

Can you tell me whether or not they are welded on or bolted on?

They are all bolted on with flanges. The front converters are bolted to each manifold and the ends are bolted to the pipes.

No special tools required.

I sent you a diagram already. I attached another one for you to view. I circled the junctions for each converter.
