Fill in your profile. We don't know if your Jeep is a four banger or a six.
Six bangers have a defective exhaust manifold. Mine just cracked while at the dunes a few weeks ago. I could weld it but it would just crack somewhere else. They sell a replacement with expansion joints for around a hundred bucks or so.
If you have a four banger, I'm sure other people know about them.
