    might be wise to wait till the warranty expires. like insurance they'll look for anything to get out of paying should something go wrong

    Hey you can do a dual exhaust as long as you leave the cats and stock manifolds, you can also do a cold air intake as long as it has a dry filter, no oil. I am sur3e a custom exhaust shop could do the duals with not a lot out of pocket, and I would suggest the volant CAI, it has a dry filter and you can find them at $275 or so for the intake and about $120 for the ram air tube. You could also do a custom tuned pcm and keep you stock pcm and swap them when you needed service at the dealer, this may be illegal and I am not saying you should just that you can. Hope this helps.

    It depends a lot on what your truck came with, but I've ran into some who feel that one of the best way to gain rear wheel hp/torque is a diff gear swap. For example, if you're one of those with 3.27 gears, and you change those out for 4.11's, you get a 25% increase in rear wheel torque.

    Again, it depends on what you have and what you hope to accomplish, but I throw that out there as another possibility.

    If you were looking strictly performance I'd recommend Edge or Hypertech Max Energy Programmer. 380-450. Magnaflow dual exhaust 300-400. K&N or Volant intake 220-375 and some new gears out back if you need them. about 400-500 installed. So That's totalling about 1300-1725. Man I can spend some money.
