Customer Review: (see review/s)
  • Muffler priced right said it was a direct fit. Not the case. I spent more on the installation then the cost of the muffler. Had to extent and add a bracket to hold it up. The least the could have do e is put a bracket on to fit the application or said it needed professional installation or not a direct fit

  • This was easy to install with a lift and welder. Great V8 sound without the vibrating or rattling, like other mufflers. Loud enough to let everybody know without waking the neighbors. Would recommend adding a coat of high temp paint to help with the rust.

  • I own a 2004 Cadillac Escalade with the 6.0 engine which has the dual inlet / dual outlet muffler setup from the factory. I wanted the 40 series, but the 40 series doesn't come in dual inlet / dual outlet setup. But the 50 series Big Block muffler does. So, I was forced to get the 50 series. Everyone tells me that the 50 series is the better choice for a refined suv such as the Caddy, because it is loud, but not offensive as the 40 series. They say, " it goes with the truck"
