+2 on the JB weld.... I had the leak on my 95 GTX and took the pipe off and had all of the plugs welded. When I put it back together, did not use locktite nor did I use a torque wrench. Well, a few hours later, the 3 nuts worked themselves off and snapped the stud on the exhaust manifold. Killed the day and caused a bit of work for me to drill and tap to do it right the second time! Being that there is no pressure on the pipe, if I had to do it again, I would grind the area and JB weld a patch over it and be done!
