VANCE & HINES EXHAUST INSTALLATION

Check the exhaust gaskets for damage, and replace if necessary. Part# 65324-83B
Remove header assembly and heat shields from protective packaging. Place each heat shield on a non-abrasive surface such as blanket or carpet. Using a felt tip pen, mark outside edge of each heat shield to show location of mounting clips that hose clamps will loop through (Figure 4).
The header assembly (D1150FC-C) will require heat shields stamped D1150HC, D1353HP, D857HP, D855HP, and D1352HP-S. The remaining heat shield D567HP will be used on the rear crossover header (D1154FC-C).
Install front headpole mounting bracket onto stud located to the right of the transmission cover (Figure 1).
Lay header assembly into heat shields and loosely install the #20 and #28 hose clamps (supplied) into mounting clips. Screw heads should be accessible when the system is installed on motorcycle for adjustment purposes (Figure 4). Position front head-pipe mounting bracket between middle and rear hose clamps. Do not tighten at this time.
Use the #28 hose clamps and install the collector heat shield (D1352HP-S) over the other heat shields. This can also be done after the header is installed if desired.
Apply a small amount of anti-sieze compound to the threads of the oxygen sensors and install them into the new head pipe. Install supplied 18mm to 12mm oxygen sensor adapter then install the 12mm oxygen sensors ( Grey connector into the front head pipe, Black connector into the rear head pipe.) Models using 18mm wideband oxygen sensors install the sensor directly into the head pipe.
Install flanges and circlips from stock system onto the new header pipes.
Using stock flange nuts, carefully install the header assembly onto the motorcycle. Finger tighten only at this time.
Install front head pipe mounting bracket onto front head pipe using A197HW and A240HW (Figure 1).
Tighten exhaust port flange nuts.
Tighten front head pipe mounting bracket.
Attach crossover pipe clamp to bracket using carriage bolt, washer, and lock nut (supplied). Note: Carriage bolt should be placed through the square slot on the crossover mount bracket (Figure 3).
Install the Torca band clamp (supplied), with nut facing down on the expanded end of the head pipe.
Install crossover pipe clamp onto crossover pipe. The open end of the clamp should face the front of the motorcycle.
Loosely attach heat shield (D567HP) to the crossover pipe (D1154FC-S).
Slide crossover pipe into header. Tighten band clamp to muffler.
Install crossover mount bracket using stock hardware. (Figure 3)
Place the right muffler heat shield (D855HP) over the exposed upper pipe of the front header section. Tighten the heat shield using a #20 hose clamp. Leave the other clip empty until muffler is installed.
Install the mufflers of your choice onto both head pipes and secure to saddlebag supports with the stock bolts and lock washers.
Check alignment of mufflers and make corrections as required.
Tighten the Torch clamps securing the crosstie and the mufflers to the head pipes.
Tighten the right muffler heat shield (D855HP) to the muffler using the #36 hose clamp.
Be sure to check that all fasteners including the hose clamps on the heat shields are tight. (See torque specifications in Harley-Davidson service manual).
Route the front (Grey) O2 sensor wire along OE path and plug into the Grey connector. Route the rear (Black) O2 sensor along the top of the transmission along the OE path and plug into the Black connector. Secure wires to the frame using supplied nylon cable ties.
Install 3/8” lock washers (supplied) on both 3/8”-16 (2.25” & 3.5” long) socket cap screws (supplied). Using these bolts re-install the floor board with two machined spacers (supplied) on the forward mount (A902HW) and back mount (A667HW). (Figure 2)
NOTE: Machined spacers are located between the floor board supports and floor board mount plate.
Re-install the right side passenger floorboard, right side panel, then saddlebags.
Be sure to tighten all hardware before starting your motorcycle.
After installation and before starting the motorcycle, completely clean pipes and mufflers with cleaning solvent and a clean soft cloth that will not leave residue. NOTE: Any residue, oil, or fingerprints will stain the finish when the metal heats up.

EXHAUST CARE

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 the 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 discoloration.
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.
