Stainless bolts
Are the bolts in the exhaust risers supposed to be stainless? I removed one to clean some rust off of it to find that some of the threads are a rusted too. I would rather just replace them all with stainless if that is what they are supposed to take.

Replace them with stainless; then you'll know and have peace of mind.:toast:

Jim, I yield to a greater knowledge. I should have mentioned that the stainless will not have the tensile strength of steel. They will stretch if tightened too much. As you said though, if the torque is not required beyond a good seal, it should be fine. To be on the safe side, the anti-seize may be the better way to go. My bad. I stand corrected.

You can try to pick that bolt up with a magnet, that will tell you if its SS or not. For an exhaust bolt, I would use a grade-8 coated with anti-seize. Dissimilar metals will react together. This will corrode the threads and bind the bolt in the manifold. As soft as SS is, the head will likely snap before the bolt breaks loose. We see this with aluminum towers and SS hardware in the joints.
