TOOLS REQUIRED
TOCK EXHAUST SYSTEM REMOVAL
- Loosen heat shield clamps on both the front and rear exhaust pipes to allow for easier access to the exhaust flange nuts.
- Loosen the clamps holding the mufflers onto the head pipes.
- Loosen, but do not remove, the exhaust flange nuts (2 for each cylinder) from each flange located at the cylinder head.
- Remove the hex head flange bolts holding the muffler to the muffler support bracket. 5. Carefully lift and remove mufflers by sliding them off each head pipe.
- NOTE: Assistance may be required.
- The stock muffler clamps may be re-used. However, Vance & Hines recommends replacing them with new clamps (Vance & Hines part # A335HW-R).
- If using the stock clamps, be sure the T-Bolt does not twist out of the groove during tightening. This could allow the clamp to loosen with use.
VANCE & HINES EXHAUST SYSTEM INSTALLATION
-
Remove the muffler assemblies and heat shields from their protective packaging. Place each heat shield on a nonabrasive surface such as a towel, blanket or carpet.
-
Carefully lay the muffler assembly into the heat shield and loosely install the hose clamps (supplied) by feeding the tail end of the clamp into the heat shield clips.
-
Note the direction of the clamp screw heads, they must be accessible for adjustment when the system is installed (Figure 1).
-
Adjust the heat shield so that the muffler body protrudes beyond the heat shield by .25 inches, and the muffler body and heat shield edges are parallel. (Figure 2). Tighten band clamps.
-
Slide stock exhaust clamps onto the nose of each muffler’s body.
NOTE: Orient the clamp in a way that you can access the nut during installation. -
Slide mufflers onto the head pipes.
-
Using 1/4” x 5/8” hex head bolts, nuts, and washers (Supplied), attach the mufflers to the muffler support bracket (Figure 3). NOTE: Leave them loose at this time.
-
Align mufflers so they sit level. Tighten the muffler mounting bolts.
-
Tighten exhaust flange nuts on both the front and rear cylinders.
-
Tighten the clamp holding the muffler onto the head pipe. Check orientation with the stock head pipe heat shield to ensure that you do not have interference between the clamp and stock heatshield.
-
Loosen the heatshield hose clamps do a final alignment of heat shields and retighten the heat shield hose clamps.
-
Check for clearance between all exhaust system components and accessories prone to heat damage.
-
Be sure to check and tighten all hardware before starting your motorcycle.
EXHAUST CARE – HELPFUL HINTS TO AVOID DISCOLORATION OF EXHAUST SYSTEM
- When installing a new set of black pipes, make sure your hands are clean and free of oil. After installation, thoroughly clean pipes with warm soapy water and a soft cloth. Dry with a clean towel to remove any residue before starting the motorcycle. Do NOT use anything abrasive to clean pipes.
- Avoid long periods of idling as this can cause discoloration.
- Intake leaks can cause the engine to run lean and overheat, this could lead to discolouration.
- Make sure there are no exhaust leaks at the junction of the exhaust pipes and cylinder head. We recommend replacing gaskets if they are worn.
