very little Joe. The CAT on your system will be the bottle neck of the breathability. You will have a nice sound if you like that sort of thing and the car may run smoother with some efficiency improvements. You may get 1 - 5 Bhp gain but then again you might not. Best way to improve is have the car chipped professionally, but this will cost you and really needs to be done with all the mods you mention too.
