as close as possible to the engine/exhaust ports - they like heat

yeah, that's right. You should mount it as close as possible to the engine, so straight after your merge.
Catalytic convertors don't actually start working until they've reached the correct operating temperature (which is freakin hot). So the closer to the engine, the quicker it will get up to temp.
When the cat is cold the exhaust gases are much more harmful than when it's hot and operating properly. I've also heard cat's are useless after 1-2 yrs of use anyway. Don't know how true that is, or if it's just a conspiracy theory...

I've been advised to have the cat placed at the original distance from the engine on the exhaust so as to meet the original emissions when built.
