Hey, Scotty

It seems to be the exhaust. Im going to change the gaskets and see if that helps. Thanks!!

Look at the exhaust system, look at the heat shields as well as for leaks or broken hangers.

pinpoint the sound, pray it's not valvetrain noise coming from the top of the engine which those often get from VVT valvetrain wear. If so, just live with it. See my video "finding the source of car noises" to see how to have the noise pinpointed IF it only occurs when driving uphill and not revving it up in the driveway
