Customer Review: (see review/s)
  • This exhaust fit my Armada exactly. It has a nice sound to it and I can feel extra pick-up when hitting the gas.

  • Was installed easy with the exception of the tail pipe end. Could not lift car off the ground high enough to twist pipe in place over axle. Took it to a body shop and had them lift it so I could install the last piece. Got it done in 1.5hrs. The exhaust system is louder than the stock and it feels like it did get some extra boost as I tested it on the highway. Overall I say it was a good buy hopefully it will last longer than the stock exhaust system.
