Exhaust leaks are common on Deloreans. The culprit is almost always an exhaust manifold gasket or two, or three. Iron manifolds and aluminum heads expand at different rates. This twists and tears at the gaskets around the exhaust ports and ruins them. The comprehensive fix is to replace the gaskets by removing the exhaust system, muffler, crossover pipe, manifolds and all. Replace the gaskets and studs that broke, then re-assemble. Easy say, hard do. We sell a kit with all the stuff.
