I have 4 friends with these trucks, and none have had any issues, and they are around 15-20,000 miles. I have had mine for two weeks, and 1000 K. Only issue, is a possible high speed vibration at around 60 -65. Might be a driveline imbalance or something of that nature. Will have to take...
Installed my GDE last week. Truck runs great, better acceleration, looks like a little better milage, no install problems, & exhaust break works well on steep grades without trailer.
