I think it may be the dreaded 4.0 850ish rpm exhaust vibration. you've described the symptoms perfectly. I understand weights on the down pipe before the Y was the factory service bulletin to solve this problem. I have the vibrations too and they are worse with an H pipe and duals. I am going to try soon with weights myself. I've read about this on a number of forums, anybody here hip to some plan or another?
