    Gain from Muffler Swap

    Hey guys

    I presently have the Flowmaster 40 series original which as everyone know don't flow that well. I was just wondering what kind of gains I would get from swapping in a set of Dynomax Ulta Flows that flow 1133 cfm.

    The car makes 403.5 rwhp on a mustang dyno and is a superchargered GT40 crate motor.

    Thanks

    Depends on whether or not you use the stickers :P

    I tend to agree with Krwy, may pick up a bit more.......
