So my muffler shop installed This muffler awhile back. They said this is the outlaw super 11. But how? It's not black and its 10 inches long. The super 11 series is 6.5 inches long. Wouldn't that 5.5 inches make a difference? My installer said its a outlaw super 10 series for my truck. Let me know what u guys think cuz I want my truck louder! Plus this muffler is rusted!
