Just wondering, I would love to get the aFe (or injen) intake + magnaflow cat back exhaust and was wondering if it will (with normal driving) increase or decrease the gas mileage that I get now (which is not that good compared to other more gas economic vehicles but I don't care).

Thanks guys
(i get about 380-400kms per tank, very minimal highway driving).
