Exhaust question?

I am thinking about removing my resonator and welding up a straight pipe. I am not sure if it was in front of or behind the catalytic converter.

Welcome to the forum. It is behind the cat. (down the exhaust, direction of rear of vehicle)

So from the exhaust manifolds to the piping and the catalytic converter,then the resonator,then piping then the muffler?

Correct.
