Except for a few racing products, all Vance & Hines mufflers come with removable and replaceable baffles -- the instructions that come with most Vance & Hines exhaust systems include an advertisement for their "Quiet Baffles." A single Allen head screw on the bottom of the mufflers holds the baffle tube in place. Although Vance & Hines warns installers to "align heat shield openings so baffle screws are accessible," the screw is often hidden under the heat shields.

  1. 1

    Unscrew the worm clamp that holds the rear heat shield over the muffler with a flathead screwdriver. Slip the heat shield off the back of the exhaust.

  2. 2

    Unbolt the four hex head bolts that hold the mufflers to the exhaust mounting bracket with a open end wrench.

  3. 3

    Loosen the end tip screw, the screw closest to the header pipe on the bottom of the muffler, with an Allen wrench.

  4. 4

    Spray penetrating oil on the muffler-header pipe joint. Wait 2 or 3 minutes, then slap the muffler with your open hand.

  5. 5

    Pull the muffler off the header pipe. Loosen the baffle screw, the remaining screw on the bottom of the muffler, with an Allen wrench.

  6. 6

    Pull the baffle tube out of the muffler.

Tips and warnings

  • It may not be necessary to remove the muffler from the header pipe to remove the baffle from the muffler.
  • Never work on hot pipes.
