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.
