Exhaust is really gonna help more with the Tone then the HP. If you are looking at HP then keep an eye out on the intakes first then make your way back to the exhaust. To really see gain though you will need a retune. Just depends on how far you wanna take it.
Anyway to answer you question, 10-15HP. Of course this is just a guess.
