You need to install the flange seals to the Y-pipe, the catalytic converter assembly at the exhaust manifold, the studs into the exhaust manifold, the exhaust nuts to the studs in the exhaust manifold, and the muffler and the catalytic converter assembly. Position the Y-pipe and the catalytic converter assembly to the flat flange and install the nuts to the flat flange studs. Then you can connect the oxygen sensor electrical connections, check for clearance and alignment, and lower the vehicle.
