Check the guide in my sig. It'll give you a basic idea on what to expect. Granted, if an intake alone gives you 3 WHP, an exhaust gives you 5 WHP, and the Shark Injector gives you 6 WHP, do not expect to gain 14 WHP from all three. You may see numbers closer to 10 WHP.
The absolute best bang for the buck mod is headers (other than nitrous). You'll gain some rasp, but you'll also gain some noticeable power.
