Hey guys. I was driving with the rear window open one day and realized that I was hearing a rattle on accelerations. I listened a little more closely and realized that it was only happened at certain RPMs, and mainly around 3200ish RPM. It seems like a harmonic rattle or something - maybe somewhere down the exhaust line maybe? I also hear it under the hood (I think) with the windows closed now that I’m listening for it more closely. Has anyone experienced the same thing?
