Exhaust Dent, Effect on Power?

[spasm3]

While putting new water pump on my sons Saturn s ( 2002) and changing the oil, I noticed this dent in the down pipe.

This engine is a sohc 4cyl, makes 100 hp.

Would this have much effect on power? Or is it negliable on a low output engine?

Absolutely no affect whatsoever.

Basically nothing when daily driving, at wot maybe but not much even then. Sure there is some difference because if not then automakers would have already made them skinnier to save on costs.

Take a look at stock exhaust on XJ 4.0s. Worse than that from the factory

My first thought, too! Everyone always thought their pipe was dented, but they came that way from the factory.

I had something similar to that happen to a 1982 Ford Granada Ghia. It was a single exhaust and the exhaust pipe got crunched like you show in your picture. The end result was some burned up exhaust valves in the cylinder head. Too much hot back pressure.
