The exhaust sounds good. I like that a lot. Thanks for posting the vid. You basically have a 3 years newer version of my truck so some of our plans might be similar. It really depends how extreme you want to go. You could even go so far as to have a long travel suspension system built for the truck rather than lifting it. It'd be awesome for offroad, desert-type runs. It's also that much more money. The best thing I can say is be realistic about what you plan to do with it. For example, don't make it into a rock crawler. You can spend a fraction of the money and get a jeep or older chevy that's already lifted and everything. Once you figure out what you'l realistically do, then decide what you're willing to give up as far as mpg as a daily driver. There's going to be give and take everywhere. You can get something more than functional offroad without sacrificing a lot as far as on road use, but the more extreme you go one way or another, the more sacrifices you have to be ok with. Personally, I'm going primarily for function in a desert climate with enough clearance for rough roads, some ditches etc.. But for the really rough terrain, rocks, ditches etc, I'm planning to get something else. What I'm also trying to do is use my truck as a proof of concept that function and form don't have to be mutually exclusive. So I'll likely be making some sacrifices in specialized offroad function in order to keep it looking the way I want. The biggest thing is DO YOUR RESEARCH. And if you decide on EXACTLY what you want, then figure out what it'll cost you and save until you have that. Don't spend money just for the sake of it, but don't cut corners either.
