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
