How's it going I'm Chad(rabbit) just picked up my 2012 Duramax which has had the system delete with a 5-inch straight pipe! I'm kinda new to the whole diesel thing so any suggestions that Y'all may have would be greatly appreciated. I'm currently adding 20x10 wheels with 33 12.50 tires and a leveling kit and tow mirrors! So far I'm super stoked about my decision to purchase this truck as for the power and torque is awesome! Hope to chat with y'all and learn as much as I can.
