I recently replaced the exhaust/intake gasket on my 96 XJ.
When I removed the exhaust manifold, I noticed that the pipe below it
had three dents just below the flare. Looking from the top, it is easy to tell
that the gas flow is restricted by the dents.
I was planning to do something about it, when I noticed that my 99 XJ
has one large dent in the same location.
Is this done on purpose to regulate gas backpressure?
Both have the 4.0 engine.
