EXHAUST LEAKING.....EGR TUBE?

[LOCASH]

Please help!!! I am going to ****ing loose it if I don't find out where this leak is coming from. I replaced the gaskets with Earl's because I thought that was the problem. I checked where H-pipe meets header and the O2's. Has anyone ever had the pipe that connects to the back of the heads leak before? It sounds like it is coming from behind the engine. Any ideas?
