VCM is a complex, over-engineered system designed to eek out a few more MPG on the highway. My Pilot (albeit a 4WD SUV), sees no appreciable mileage benefits from VCM. In fact, with the Muzzler installed, I'm getting 0.5-1 MPG better. This is because I'm no longer accelerating out of the annoying NVH of the system around town. Some people are more sensitive to NVH than others. If you notice it, the Muzzler is a great way to tap into the full power & smoothness of the J35 -- a fantastic engine when not neutered by VCM. If you don't notice anything, I still advocate the Muzzler as a way to save your spark plugs and rear engine mount -- both known to prematurely fail from constant cylinder activation-deactivation.

Well said. I might mention as well that the VCMuzzler is simply a plug in device, easy enough to remove every time you visit the dealer and they will never know it was there.
