Thank you for the questions
1. We always recommend replacing the gaskets when replacing the exhaust manifold or upgrading to a header, this way you have the best seal possible.
2. Since you are doing the headers, a overpipe will help further increase performance a little bit and reduce restriction. Plus while you are down there, might as well upgrade the overpipe. We know that the headers are the biggest restriction in the exhaust system for the twins.
