Check your exhaust output, if a smooth hiss and not puffing, also seems hot and would steam up a mirror, then there is a blockage.  This could be in cat or a silencer section.  Unbolt in front of cat or remove oxyen sensor to test, if improved, move down to test other section before replacing the cat.
