I bought and installed a PAI I found on 1aAuto.com for my 2007 LT 5.3.  Installation was a breeze, parts are good quality and everything fit very nicely.  All this for only $80.  So far, after driving with it for a couple of weeks, I am averaging 1-2 mpg better than with the stock system.  (I have also done the resonator delete with the SLP tips.)  Next purchase will be a tuner.

I am so glad I didn't spend $160-$350 for a name brand system that is essentially the same thing.

There is only a noticeable increase in sound when you really stomp on it.  Getting rid of the resonator gave it a much nicer sound all around with absolutely no drone at highway speeds.
