Hey, I see you have airaid CAI.... I have the drop in and I am looking at corsa exhaust... I am at high altitude (10000 feet) and everyone is telling me ya you need or no its a waste.... do I really need a CAI with the corsa or will my drop in synthamax be fine? it already boosted response... I really want to know if adding CAI and exhaust combo makes THAT much HP..... thank you... btw your truck is so damn SWEEEEEEEET!!!!
