The straight pipe was s surprise. I was expecting the really LOUD rumble like you get from a small block gas motor. It is not there at ALL. What I do hear is a little more of a throaty rumble from it. I cannot tell a difference in the cab with the windows up. At the Dynoday today it did sound a little louder than the rest but to me it was nothing like what I had expected. I really like the straight pipe. If I decide to get the Kennedy 4" I will get it straight with no muffler.
BMDMAX has the 4"Banks and it sounded REALLY nice on the dyno. But at idle it is still quiet. I think he is just trying to pull a sleeper on us.
That guy put down over 500 HP today!! It was SUWEET!
