Not an engineer, but wouldn't the computer simply compensate for the increased air or efficiency increases by reducing fuel to maintain temps or other parameters in spec? It would seem that without a reflashed computer to take advantage of the efficiency gains, all you're doing is dress up an otherwise underwhelming engine bay. If you went for the whole package, you're looking at 3-5 grand and you give up a warranty. Although If you have that kind of money, maybe the warranty isn't critical. I may be making a broad oversimplified presumption. However, I do want the exhaust because the stock exhaust is so horribly large.

I am sure those parts would work better with a tuner. Typically, you have to make changes to the computer in order to put the increased efficiency of the better flowing aftermarket products to work...

Warranty is another issue altogether. The owners manual even says "no modifications to the exhaust". Personally, I will wait until my warranty runs out before I make any changes. For the more litigious people, you can always refer to the Magnuson-Moss Warranty Act where they have to basically prove that the aftermarket part was a direct cause of the failure that is being denied under warranty coverage. I am sure that the manufacturers would go out of their way to deny all kinds of warranty items if it wasn't for that law... "Oh, you added an aftermarket tie down ring on your bed, that voids your axle warranty..." The examples could be endless...

i went with the magnaflow exhaust just because i liked the sound better and it comes with the o2 sensor. i know the afe intakes will throw codes like crazy but like you said, if you tune it then its not a worry

Good points Ternaryteacher. Since the advantage is to the dealer, any effort to get satisfaction from the OEM after an aftermarket installation/warranty dispute would come at some expense. Probably far more than the problem you're addressing with the dealer. Better to wait. My dilemma, I opted for the extended warranty since I could easily run this through the mileage limit before the time component. I like the AFI because it doesn't add a muffler and it improves the look at the tip. I think I might just take this up with my servicing dealer to see how they react. Option B, polish the tip.

Would you be able to put up a video of it driving by? I would love to see what it sounds like in comparison to stock.
