  1. RB

    The muffler is compact, flows well, has a deep tone, and produces no drone at highway speeds.

  2. JD

    Muffler eliminated cab drone while keeping a strong exhaust note. Good balance for daily driving.

  3. ED

    On a deleted 2022 F-250 with a 4-inch straight pipe, swapping in this muffler restores a factory-like sound with no highway drone.

  4. AW

    The muffler reduced noise just enough after a full delete. Install was simple and the volume is now comfortable.

  5. BH

    Muffler fit well and performs as expected.
