1) Seems there are two types of catalytic converters for the 92 Accord EX.
How does one tell which aftermarket converter to buy as a replacement ?
Suggestions welcome.

2) Can the catalytic converter be replaced without completely dismantling
the exhaust sytem. It is bolt-in, and there appears to be a flexible mesh
cover over the solid segment of exhaust pipe on the engine side ahead of the
cat. But it looks like the post-catalytic segment needs to be lossened to
install the cat.
