View Full Version : '91 Prostar - Exhaust redo

10-15-2012, 04:50 PM
Based on feedback from a previous thread,


I have some work to do on my exhaust system.

Below is a pic I took to point out a leaky "freeze plug". It also shows a pretty rusty exhaust manifold.


So I think I need to do the following:

1. Remove the risers, inspect and replace the manifold to riser gaskets.
2. Remove the exhaust manifolds (?), inspect and clean up the manifolds.
3. Replace stuff that is no good.

Here are my questions:

1. What exactly am I looking for to see if something needs replacing? Would a crack be obvious? If they are rusty and nasty inside, is that a reason to replace?

2. If I do need to replace manifolds or risers, any suggestions on mfgs or mfgs to avoid?
