adding Converters to my O/R H pipe

Now if I were to buy Cat. Converters for my Off Road H pipe on my 1992 5.0

Where would I have to put them on the pipe. I see some mid pipes with the Cats near where the headers connect to the Mid pipe and I see some where they are down near the where the mid pipe connects to the cat back.

Does it matter where they go on a 5.0 OBD I?

Dont know if they have to go before the O2 sensors or not on a OBD I

After the 02 sensors, right after the exhaust bends and goes horizontal to the ground.

ok cool!!

Will any universal Converter work?? I notice there are different lengths ect.

I will need a converter for a 2.5 inch pipe

anyone one the last question about which cats can i use??

Does ANYONE know what kind of cats I can use to put on my H Pipe??

there is so many different kinds and sizes out there
