How much if any power would i gain from adding a custom dual intake(with battery relocation) and a custom dual exhaust from the cat-back. Would this be worth it? any tips on how i would run 2 MAF's. thanks!

to run 2 MAFS you would have to get your ecu reflashed which wouldnt make a major HP increase even with the cat back...maybe 5-10hp...

so i am better off with the stock intake, assuming it is not cheap or easy to get the ecu reflashed.

the stock intake is fine...if you were running bigger injectors and needed more fuel then of course you would need more air...if you want to make it better invest in a K&N filter or go with a cone filter and remove the stock airbox...note that if you do remove the stock airbox the motor will seem louder as you will be able to hear it suck the air into the intake

hehe, louder from the airbox until you do the exhaust. Then you won't hear the intake at all.

Stock intake is as close to CAI as I can get.

yeah i am already running a K@n drop in filter, for exhaust i am going to run straight pipes to dual tips from the muffler back. it is pretty cheap way to hear some nice sounds
