Hi, I have an 09 cobalt ss. I did a 3inch downpipe, drop in k&N and trifecta tune. car runs strong. I decided to keep it. Just bought clack chrome o.e.m. rims so now I am itchy to throw more at it. Recommendations please? I was thinking cold air intake(which one is best), stainless cat back(which one is best?), intercooler(which is best), new turbo?? I just run around on the street. Might drag her once. Please make any suggestions and would appreciate help with who offers the best deals. THANKS GUYS, I APPRECIATE YOUR HELP

 

For catback, go MPx, for intercooler, I would say zzp. If you get an intake retune, and K&N intake. Do you still have stock charge piping? If not replace that. ZZP on that too.
