    Gas or diesel? Either way you will see little power or mpg gains. In a diesel it might drop your EGT slightly if you have a true cold air intake. Im guessing gasser though since you said Flowmaster.

    But what are you really asking about cause you cut yourself short.

    If he's asking in reference to a diesel, then ignore my post. I've not yet owned one. But if you're thinking of spending money on a CAI and a Cat Back Exhaust and expecting real performance gains.

    CAI's often cause lean conditions on most gas engines. Some years and models are more suseptable to this. To get any real gain from a CAI, other then noise, you will need a tuner with custom tuning that adjusts fuel curves and all to take advantage of the extra air. Then theirs the cat back, it's really not going to give you much more then extra noise. At least it doesn't create the lean condition the CAI can. Be careful positioning cat back tail pipes, as some run kind of close to the spare tire.

    The short of this is. Don't waste your money.
