lt's too low

FWIW, I had a similar problem with my exhaust a year or so ago on my notch. Exhaust was drooping down about 2" on one side no matter what I did. Turns out, the passenger-side motor mount was FUBAR. The rubber had deteriorated to a point where it allowed the motor to fall in upon itself and nestle down into a little corner of the motor mount, which resulted in a lot of headaches with getting my exhaust stuff to fit worth a poopie. Replaced the motor mount, and TA-DAAAAA! Everything's straight, now.
