My oil is completely topped off since I just changed it. It almost sounds more like a metallic buzzing noise, someone else mentioned tightening the heat shield for the exhaust, but I don’t think that’s it either.Start with something simple check your engine oil levels make sure it's not low
Now that you mention it, I put a short ram intake on about a year ago, but I put the stock air box back on pretty quick after due to a loss of power from the after market intake, ever since then that’s when the noise started, maybe I’ll go back and double check if everything on the air box is tightened proper.doesn't sound like a heat shield, but its faint and indistinguishable in the video.
air intake possibly? you have a stock intake and airbox?
