3g hemi gas mileage

Well the dyno day is out, got to pay off some bills as my printer doesn't seem to want to print out any money, lol! I did get some Flowmasters cause the Dynomax's are just to friggin' quiet. Since I'm gonna be redoing the exhaust, I might just beable to get those cats on....we'll see. Who knows, the Flowmasters may just wake up the hemi and I might get a tad better on the mileage.
