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. 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. Unbolt the four hex head bolts that hold the mufflers to the exhaust mounting bracket with a open end wrench.
3. Loosen the end tip screw, the screw closest to the header pipe on the bottom of the muffler, with an Allen wrench.
4. Spray penetrating oil on the muffler-header pipe joint. Wait 2 or 3 minutes, then slap the muffler with your open hand.
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. Pull the baffle tube out of the muffler.
