Are you sure that couldn't be leaking from the fuel tank? Never in my life have I seen fuel get all the way through and a catalytic converter and a muffler. The Converter gets so hot that it would ignite long before getting through it anyway.
You certainly could be having some kind of flooding problem and that would take an injector balance test to determine if one was leaking. Usually when that happens, the gas runs down the cylinder walls and into the crank case and dilutes the oil and not the exhaust system.
