[EvoX95123]

I have taken my MR back to the performance shop twice and had two different people double check the tightness of the bolts and clamps. There are only two bolts and two clamps to check.

The folks at Perrin told me that my Evo is the first one that has this issue. Very odd!

I am wondering if the additional sound insulation of the MR package happens to resonate with Perrin's exhaust note. I notice the Perrin CBE has a deeper exhaust note than stock. MR has additional 18lbs of insulation from my reading. Well, just my hypothesis...
