I have a 1990 Chevrolet Cheyenne truck. Recently, the exhaust pipe came off. If I don't have it replaced, can it do damage to the motor or in any other way to the vehicle if I keep driving it that way? It's kind of loud, but it's not that bad. I've been driving it without the exhaust pipe for awhile and have had no problems so I'm wondering if it's crucial to have it replaced or not.

That's not a real good idea, depending on where it's broken. The further forward, the worse it is. If it's broken before the oxygen sensor, it will mess up all kinds of things. Anywhere in the forward area will cause exhaust fumes to get into the cabin and that is dangerous. The reduction in backpressure can damage the valves also.

Quick reply - heat in the wrong places can be not just dangerous but deadly!

I don't know. I hear conflicting stories behind the cracked valve cold air theory. I see boats run open headers all day long and don't burn up or crack valves.

I think on some of these when you uncork the exhaust you reduce the back pressure which can cause a lean condition if you don't compensate for it. A lean condition can cause burnt valves.





Since we volunteer our time and knowledge, we ask for you to please follow up when a problem is resolved.
