Install time?
 

i am ordering a 4" diamond eye turbo back duals exhaust system, 4" diamond eye down pipe and an Air Dog 150.

I am also goin on military leave for ten days in the begining of May. I told myself i wasnt goin to work on my truck while on leave but i know that is not going to happen. So my question is about how long on average would it take to install these things in a "perfect" world. I figure if i leave myself one day i should be able to get all these things done.

thanks,
josh

The exhaust is takes about 1-1.5hrs and when I did the airdog on my dodge it took me about 3 hours and that included taking the bed off. I would add another hour to the airdog just because I don't know anything about hooking an airdog up to a duramax

The down pipe will take you the most time. Its a Pita to get to.
