Drove the XRunner to lunch today. This is the new Spec-U header back exhaust system to go with the URD Spec-U headers. Decided to do a couple of videos: Normal driving up to posted speed +30. Cab is very quiet at high highway speeds. Rolled the windows down and got on it a bit. Seems to be a tad traction limited. Normal driving windows up. Getting on it a tad with the windows up. Parked back at URD with the windows down.
