VANCE & HINES EXHAUST SYSTEM INSTALLATION

1. Attach mounting bracket 390-P to transmission and tighten to 12-15 Ft/Lb torque. (Figure 1).
   NOTE: 2006 to 2009 models use three 5/16” x 1-1/2” hex head bolts and washers. 2008 to 2009 models use three 5/16” x 1-1/2” hex head bolt, washers, 11/16” spacer between the bracket and transmission in top hole.

2. Remove head pipes from their protective packaging and install circlips and flanges from the stock system onto both new head pipes (Figure 2).

3. Apply a small amount of anti-seize compound to the threads of the oxygen sensors and install them into the new head pipe.
   NOTE: 2006 to 2009 models or models using 18mm wideband oxygen sensors install sensor directly into head pipe.

4. Remove heat shields from their protective packaging. Note: Removal of end cap may be required. Place each heat shield on a non-abrasive surface such as a blanket or carpet. Using a pencil, lightly mark outside edge of each heat shield to show location of hose clamp mounting clips (Figure 3).

5. Lay header into heat shields tail end first, engaging end caps.

6. Install end caps (if removal was necessary) into tail end of each heat shield engaging head pipe and heat shield. Align mounting hole with end cap hole. Install and tighten 1/4”-20 button head screws.
   NOTE: Removable thread locking compound is recommended.

7. Loosely install hose clamps by feeding tail end of clamp into heat shield clips (Figure 3). Use #20 hose clamps for head pipe areas and #28 hose clamps for muffler areas. Take note of screw head direction (Figure 4). Screw head should be accessible when system is installed on motorcycle for adjustment purposes.

EXHAUST CARE – HELPFUL HINTS TO AVOID DISCOLORATION OF EXHAUST SYSTEM

1. 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 clean towel to remove any residue before starting the motorcycle. Do NOT use anything abrasive to clean pipes.
2. Avoid long periods of idling as this can cause discoloration.
3. Intake leaks can cause the engine to run lean and overheat, this could lead to discoloration.
4. 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.
