I am a do it myself kind guy, the only thing I will pay others for is when I re-gear the truck to a 4.56... But just a heads up, by no account were the headers an easy task; the driver’s side is fairly simple, but the passenger side required the engine to be lifted, but top to bottom it took 2 dudes (My neighbor and I) roughly 6-7 hours, I'm sure if we were to do it again, it would be faster, but the instructions that came with the kit were fair vague, and trial and error played a part of the amount of time...
