    I've had my exhaust (Flowmaster dual 50 kit) on for about 2 months now and I can't make any determinations about gas mileage. About a month before I installed it, my MPG dropped to 15-16mpg and I'm pretty sure it's because of the winter gas. It's been like that all winter. All summer last year I was getting 18-19mpg. So I'm hoping when spring/summer comes, it'll atleast get back up to what I was getting last year (or better). We'll see....

    I believe it's a 50 series and that is quieter than the 40 series.

    Do you know the model number?
    I have the #17432 which is dual side exits. It's 50 series.

    I ordered mine here. I looked up both prices and this place is $30 cheaper than Autoanything and also has free shipping.
    http://www.wundercarparts.com/searc...r=Flowmaster&gclid=CPL_jIylopYCFQNfFQodbQxz5w

    The 50 series is quieter than the 40 (from what I've read).

    I have the TRD exhaust system installed. It is difficult to tell what all has changed about my truck and the intake system but from what I can tell I was running about 18.5 mpg prior to the exhaust. Post exhaust I am running about 19.7 mpg.
    About the same driving conditions nothing really changed there.
