HAHAH... sweeeeeeet.. Your's sounds the same as mine, in cab, but man, is that loud in the rev one.. im gonna have to let my buddy do a drive by of me, so i can see if its that loud, jeebus. hahah NIce stuff.
Sorry for the late reply but Hurricane Ivan decided he needed my computers (and house!!!) more than I did so I have been down for awhile.
I should mention that the REV wave was taken with the recorder on the ground right below the exhaust tips. It really isn't all that loud when you are just standing next to the truck. Everyone who heres it says it sounds great.
WixedX - This is just my opinion but the Flow's seem to have a "tin can" sound that the Dyno's don't have. I like them both, but prefer the Dyno's.
