what up fellas? I have a 2003 4.3L Xtreme. I was wonder what the baddest sounding cat-back system there is?? I am in a toss up between all the exhaust companies (i.e. flowmaster, magnaflow, edelbrock, etc....) I was just wondering what you all are running, what you paid for it, and where you got it (i.e. local store, jegs.com, summit.com, etc...)???? thanks for all your input.
