So I have an appointment at Cobb tomorrow morning at 10 and I am getting a few things done. One I am getting the CAP (access port) and from what I hear its the best bang for the buck, also getting the Cobb downpipe, Cobb cold air intake and air box. I already have the SPT exhaust and short throw shifter. Question is...how much of a difference will I notice? What are some things that will obviously be different and how long will it take my car to adjust to the changes if anytime at all? Thanks in advance I'm very new to modding cars I have been racing motorcycles for a few years and im branching over to the car aspect of things now. Appreciate the advice/help.
