Do Grand Ams have catalytic converter gaskets? Mine did not have one on either side.

I believe only after the cat where it connects to exhaust.

There should be a gasket between the catalytic converter and the resonator. There is also a metal ring gasket between the Exhaust Manifold and the down pipe.

The one between the cat and resonator tends to blend in with the rust layer, if not just disintegrate.

Both are quite inexpensive.

What kinds of problems could you get from not having a catalytic converter gasket?

Exhaust leak.

I found the two gaskets

However I don't see how the second gasket is supposed to fit between the resonator and catalytic converter since it has 3 bolts when this gasket is made for two?

Here ya go....you need a 3-hole gasket to fit between the cat and cat-back flanges.

I personally had to special order that gasket from O'Reilly's. This was before we installed the exhaust but I really did not feel like waiting another week to get it installed so we just used high heat exhaust sealant and its been fine since.
