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

  • Sounds good on my 2005 ford explorer. Nice rumble without it being obnoxious can still talk over the noise levels it produces. Plus it is half the size of original muffler that came with the car.
