Dual exhaust is good for about 10 HP dont go over 2.5" on a stock motor, you will kill your low end torque.
I believe the Maraurder airbox and MAF will give you about 15 hp but the airbox and MAF cost about $200, and then the chip you have to have costs another $250-$300
A K&N MIGHT give you about 1/2HP at 7000RPM, but it allows more dirt past the filter and into the engine, and if it is installed when the oil is not completly it will screw up your MAF. sitck with a paper filter the biggest restriction on a 4.6 is the heads and intake, so until you change those a K&N is about worthless.
If you want cheap power buy a Box panther
