i have a megan test pipe on my car(before any tree hugging hippies bitch, i bought the car with no cat on it, and when i did the exhaust and i realized there was no cat, i didn't have the money for one, so i bought a 20 dollar megan test pipe, but anyway) Now i need a cat, its got a b18c and the header i have is one of the long ones with the 02 sensor bung on the header(for some reason some are short and without the 02 bung) so I've been long winded enough. anyone know what cat i need? gsr? ls? civic? thanks

if you are gonna get a cat just go get one made at the muffler shop. it will be a good one for sure.

First, we need to know what kind of car you have. Year? Model?

FYI There are usually 2 - O2 Sensors on the exhaust. 1 on the header or before the cat & 1 on the Cat, or behind.

its a 94 cx, and its obd1 so it only has one 02 bung before the cat, and thats on the header. so i need one with no 02 bungz. i can measure my current test pipe for length, but i dunno which cat's have 02 bungs in them. i'd have measured it already, but its like 5 degrees outside. so i anyone knows, great, if not i'll freeze my ***** off and go measure it

Most Cat's you buy if it does have a O2 Bung will have a plug so no big.

I just bought a cat, but it was 1" short.
