Default Help on Civic 96-00 catalytic converter compatibility

I need to replace the catalytic converter on a 99 Civic Ex coupe, i wanted to know if all the 96-00 civic coupe/hatchback cat's were compatiable with my car? I know the catalytic converter off a 99-00 Civic Si will work but will the dx/cx models work? LMK thx

They are NOT compatable.

DX/CX are built into the exhaust manifold(header) right of the side of the engine in the front area of the engin bay. The EX and SI have it after the exhaust manifold under the car.

See pic
#4,5,6 & 7 is the EX/Si converter. This image actually shows both DX/CX and Ex/Si system. Not sure about GX.


And this is the exhaust manifold for EX/Si:


In this pic:
This is ithe exhaust manifold for the DC/CX HB models.


and the rest of the exuast system:
