It will work just fine, just not for very long.

Aftermarket cats are cheap largely because they aren't made as well as OEM
cats. You'll get at least two years out of the aftermarket job, maybe one
or two more. An OEM cat is good for 15 years.

Unless it is on an Odyssey. On the Odyssey you need a cat that is designed
for large volume which most general replacements aren't.

You mean you'd need a cat designed for the gas flow from a 3.5L V6 instead
of a 1.5L four. If you put a 4-banger cat on the V6, you wouldn't be going
anywhere very quickly, and your MIL will probably come on.

If you read the threads on odyclub.com on replacing the Odyssey converter
with an after market Converter very few succeed. Most have problems with the
code returning shortly after the replacement probably due to the tight specs
of the computer and the volume of the 3.5 engine. Replacing the converter on
an Odyssey I would get a written guarantee that it will work....

Hm. Then it would appear obvious that the aftermarket cats in question
have not sufficient fluid flow for the 3.5's needs.

Considering the aftermarket makes cats for engines as large as seven
liters (or 3.5 liters per bank), somebody's getting pretty poor service
somewhere...
