Checking exhaust system for leaks

If you suspect the leaks are in the piping just remove the collector connection and plug the pipe at the front. That's probably the easiest way. If you find no leaks in the pipes/mufflers then you know it in the headers/manifolds. You could plug off the carb (rags) and check everything. Be prepared to use two or three cigarettes/cigars to fill the whole system.
