Yes, the 99-03 7.3 PSD is known to eventually have leaking up-pipes (these connect the exhaust manifolds to the turbo collector "baby's butt"). If you get the bellowed up-pipes (available HERE from ITPDiesel) you'll get everything you need and probably never have to do them again.

I've got another question, has anyone had soot coming from around one of the exhaust ports between the manifolds and the heads? Mine does and I'm planning to do all of the pre-turbo exhaust in the next two years with new manifolds and the bellowed up pipe kit.

the only leak we hear most about is where the exhaust back pressure sensor (EBPS) tube goes into the head..its at the front of the manifold passenger side..
