Different cars/dynos, but that's about what my car made bone stock. Cat back will net you almost nothing, 2-4hp most likely. Good header/DP will help, then put a smaller pulley on there. No reason to run 60lb injectors and only a 3", you can run a 2.9 with stage kit 42lb injectors. Drop down to a 2.7 after you do exhaust, will be around 250-260whp, then do cooling mods.
