If you get the Stillen front bumper you gain abour 15HP but only 9HP without the bumper as tested on a dyno by MotoIQ Review and Independent Dyno Test

The Stillen exhaust sounds absolutely great and adds about 18HP. The combo definitely pulls harder than stock.

Gas mileage is most likely the same.
