    I am in the process of pulling the well worn stock (maybe OE) exhaust from by 225 equipped CJ5. I ordered a stock replacement set up from Waldron Exhaust and thought I would go ahead and pull the old system while I am waiting on the new one to arrive.

    I expected the biggest challenge to be where the pipes connect to the manifolds. With a little heat and Kroil the left side came off no problem. One of the 1/2" bolts screwed right out and the head snapped off the other with almost no torque applied. I'll use the easyout on that when I get the exhaust completly removed off.

    My problem is with the right side manifold connection. The pipe appears to be mounted to the manifold with two studs and nuts. The studs are fixed in the manifold and the exhaust elbow collar slips over them. Is this a standard set up?

    Also, the nuts seem too small to get a 1/2 socket on and a 9/16 socket is too large. Any suggestions as to how I might remove these nuts or even the complete stud?

    I would soak them down with Kroil, as you mentioned. Have you tried a metric socket? Even if the nut/bolt wasn't metric originally I've run across quite a few that corroded down to the point where the correct sized socket would slip. Also, make sure to use a 6-point socket! You may ultimately end up cutting off the old pipe and removing the manifold so you can cut the old stud off and drill/re-tap the manifold for a new one.

    Back in the day when I did almost all my own work I used to always chase the threads on manifold studs, and then use brass nuts on reassembly. That way they don't gall together. If all else fails, you can heat the brass nuts to the point where they will release and they won't damage the studs.

    Thanks Steve. I've been thinking about a 13 or 14 mm socket.
