It only happens at exactly 1800 rpm. I put it up in the air and tried free-revving it to see what was vibrating, but everything seems solid. I've followed the entire exhaust system from the exhaust manifolds to the muffler and nothing is touching or loose from front to back. All exhaust hangers/bushings are in use and tight.
