I just picked up my 2018 Z71, and am looking for advise to get the maximum out of it. I have already installed an K+N cold air intake...which yielded some marked improvement in the performance in the lower band. Next...what about a cat back system? what about the AFM that everyone gripes about? Not looking to make this a crazy build, just looking to maximize what I got. Also...not looking to blow the neighbors away with the noise. Just something efficient and effective. thanks...
