exhaust leak

Hey fellers,

I finally found my exhaust leak. The pipe that connects to the resonator (i think resonator) looks as if the top half is missing. When I look from the drivers side behind the front wheel and someone revs the engine I can see exhaust flow out on the top half of the pipe on the front side of the resonator. Is this a two piece pipe or do I have a hole? It should be the original exhaust which is stainless (its a '92 LSL) so i wouldn't think it would rust or corrode. Just dropped it off at the muffler shop, what should I expect to fix this and ~ cost?

thanks
