    Get you a set of LT's cat back and then tune it. That should do you some good, if you are not happy then......SC it!!

    An exhaust combined with your cold air intake will yield some more hp gains than just an intake by itself. If it were my truck, I would go intake, exhaust, chip or custom tune, headers, cam, forced induction (in that order).

    Welcome to the club. Unfortunetly HP stands for horsepower and high price. As ajarman said long tube headers, cat-back exhaust and a tuner, I like the Diablo Preditor. If you buy cheap headers and exhaust they just won't last. Save your money and get the good stuff.

    Seriously, these spam accounts are really annoying. When I log into the forum I report spam at least 2-3 times a day. Steve, if you're reading this, is it possible to upgrade the anti-spam software for the forum????

    I'm confused. It seemed like a legitimate question to me.
