2007 Silverado free mods?

[acmerkt]

I just picked up a new 2007 Silverado Z71 crew cab with the 5.3. Are there any free or next to free mods for this truck? I have a rough country leveling kit on order for the front end, and thinking about getting a K&N kit for it as well. Thanks

i think you can do a TB bypass. my mom has a 2007 4X4 avalanche with the revised 6.0. we put dual borla on it and it sounds wicked. but when you're on the hiway you can hear it switch back and forth to v4 and v8. maybe she needs an x-pipe. i would stay away from the k&n cuz it does not filter as good, you get good air flow but some dirt gets by. we put a AEM brute force CAI on it as it was cheap off of autoanything.com and filters excellent. could definatley feel a difference, sounds great and looks awesome. check it out...
