and I had no vibrations then, or with the Nismo mount. I have the same 1-pc driveshaft as I had before the mount swap. I too compared the mounts and the mounting holes and exhaust hanger stud locations were identical. The ride height was the only difference. The down pipes, test pipes, and hanger studs all move in unison, so the only opportunity for exhaust misalignment is at the flange between the test pipes and the cat back (h-pipe, x-pipe, whatever). Driveshaft angle changes slightly with tranny ride height, but again look how much mine changed with no vibrations in either position. The driveshaft should not be sensitive to such a small change in operating angle. For those who claimed a difference in vibration between the stock and Nismo mount, I suspect that the identified vibrations are there all the time (ie. something else is wrong), the stiffer Nismo mount just makes it more noticable. That or maybe there really are two different Nismo mounts out there as Kyle mentioned?
