So I pressurized my exhaust a soap and watered my exhaust manifold. Discovered 5 leaks. 1 and 2 are exhaust gasket issues as there in between the engine and manifold. 3rd is the downstream O2 sensor, 4th is the top bolt where the lower exhaust pipe bolts to the Catalytic converter and the 5th is on the underside of the front catalytic converter portion of the exhaust manifold (not in view from top). So I plan on removing tomorrow. Photo attached of three of the leaks.

Any recommendations on repairing this? I really don't want to buy a new one at about $500.
