So for a Nationals-style course, we're going to have to increase our power as best we can. Does anyone have any definitive numbers on what a cat-back exhaust can do for the power output of the FiST? Has anyone researched it such that I can be lazy and allow you to post your extensive research in a reply to this thread? I'd particularly like the numbers as they apply to 1st and 2nd gears. Correct me if I'm wrong, but we don't get all 197 horses until we hit 3rd gear, right? So does an exhaust help more or less so, compared to stock in 1st and 2nd gears? Just grasping at the last possible performance gains we might be able to squeeze out of this car for Nationals. Thanks!
