I just noticed that my crossover exhaust pipe, that runs from the front manifold to the rear, has a hole in the outer shell about an inch square. This is the first time I knew that this is a pipe within a pipe. Can someone explain this to me? Is the outer pipe just a heat shield? Should I have this hole welded, or just leave it alone?
Thanks

there should be a flexible hose that connects from the exhaust to the air cleaner assembly. There is a damper door in the intake that uses the hot air from around the exhaust until the motor warms up in cold weather. Put a new hose on or you'll will be heating everything up under the hood. Any parts store will have them. Pretty much universal.
