Determined

Nice, I have the Range modular , I take out every now and then and let Lifters/cylinders do there thing, I hope she last awhile I love the truck

How many miles to get out of a 14 Sierra slt 4x4 5.3L? Currently 118k , try to take best care as much as possible

The dealer ship had the lifetime warranty on this truck,,,,, I know I got lucky , they are hard to come by

Good question, but we all know it won’t be like a flownasyer 40 with resonator delete kinda loud . I would like to have it loud not how the sails are from the factory and little rumble

I have a lifetime warranty on my Truck, I am tired of the electric noise , “super quiet”. I want to throw some cat back exhaust on, resonator delete or a new flow master 40, something , with a 6inch tip, Welllll the dealer told me to call there warranty people and the warranty people said any modifications to that part of the vehicle WILL void the Lifetime Warranty, I already had a new tranny rebuilt and new driveline:differential seal installed also wheel bearings ALL UNDER LIFETIME WARRANTY, So it has been a huge help, So can I or can I not do a simple exhaust without voiding my lifetime warranty ??

I just installed HID’S in my 2014 GMC Sierra slt 5.3, I unplugged the Mass air flow sensor to get airbox out and plugged it back in to start up got fans running and check engine light on ?? It’s been sitting for 3 hours during the light install . Now it runs with fans on and engine light on ? I turned it off cause I didn’t want to drive it
