For the last several weeks I have been hearing a popping noise similar to when a rock flies up under the truck. It seems to be coming from the area near the catalytic converter, similar when the truck cools down you hear the "popping" noise. It seems to only do it for the first five minutes or so, like it is coming up to temperature.

Anyone experienced this??

Thanks, I was looking for a broken weld in the heat shields at the Y-pipe and Cat, I agree with you on this just have not found it. It just bugs me to hear it popping.

Thanks again for the comments
