Welcome,

there's quite a few items that will increase those ponies while keeping the VG33E's thirst about the same.  Some will actually improve your mileage if you can keep your foot off the floor.

Well considering you're not racing down a drag strip or anything along that sorts, nor is your motor pushing over 500 HP... exhaust is a purely selfish thing.  By that I mean find something that makes your truck sound good to YOU.

my .02 here as well... cat-backs are a complete waste of money if they're over $350 just for the kit not including labor.  A local exhaust shop can put your muffler on for you anywhere from $50-$200 depending upon if you want dual exhaust with tips.  Plus the price of the muffler you want to give you sound you want.
