I am sponsored by Massiv USA through their introductory offer of 2 free exhausts to the most qualified takers offer maybe 2 months ago. In order to do this test I paid like $35 shipping and had to buy the TurboXS catback adapter to turn their proprietary length downpipe into a standard length. That ran me like $125 if memory serves. In the end it wasn't totally free, but it was damned cheap.
My apologies and I have to wait until this weekend for a full review....it's coming I promise and there's a reason why I have to wait that will be explained.
