Hello my fellow enthusiasts. New to the forum and I'm trying to narrow down some good info. Just picked up a cherry loaded 2011 Tahoe z71. It's bone stock and ready for some performance upgrades. I'm no dummy to the auto repair trade so I know the general stuff but I'm looking for the the first hand knowledge of what really helps add the power and what sounds the best. Looking for a nice rumble but not obscene and of course the best bolt on mods to get some power that I can actually feel but nothing to crazy like turbo kits. Can anybody help me out?
