need some help on exhaust for 92 integra LS 4 door 5 speed

Thanks to "slow ej6" for the info about the catalytic converters.
i am not a mechanic, and i am not sure i will keep the car. i just wanted to make it legal to sell or drive.
some other acura list had suggested if i wanted a cheap cat, to try a bosal.
that is all i know about it.
my sister said that the honda dealer had quoted her something like 1400 bucks for a new cat plus the installation...that sounded outrageous.
so i went to a precision tune (a step up from a midas muffler shop) and they told me 450 to 500 bucks for a new cat with the installation.

so i was just checking around.
thanks again for the info.
Sincerely,
TMH
