proper battery removal.
Unplug the front sensor (located behind the rectifier) from harness and feed the
end of the wire through the frame, freeing it from motorcycle.
On FLSTC, FLSTF, and FLSTN (floorboard models), loosen the right hand floor
board mounting bolts to gain clearance for exhaust removal and installation.
Loosen the heat shield clamps on both front and rear exhaust pipes.
Remove the two mounting nuts from each head pipe, located at the cylinder
head.
If equipped, unbolt the carriage bolt and clamp attached to the bracket under
the right side transmission cover.

Install bracket (stamped 352-P)(supplied) using the two lower holes in the frame
below the right passenger footpeg, using two 3/8”x3/4” flange bolts (supplied)
(Figure 1).
Remove head pipes and heat shields from protective packaging. Place each heat
shield on a non-abrasive surface such as a blanket or carpet. Using a felt tip pen,
mark outside edge of each heat shield to show location of hose clamp mounting
clips (Figure 3).
Lay head pipes into head pipe heat shields (Figure 2) and loosely install the
#20 hose clamps (supplied) into mounting clips (Figure 3). NOTE: Muffler heat
shields will be installed after pipes are on the motorcycle. Screw heads should
be accessible when system is installed on motorcycle for adjustment purposes
(Figure 4). Do not tighten at this time.
Apply a small amount of anti-seize compound to the threads of the O2 sensors
removed from the stock head pipes and install them into the new head pipes.
NOTE: Install O2 sensor with gray connector (short) in the front head pipe and
the O2 sensor with black connector (long) into rear head pipe. Be careful not to
get anti-seize on sensor tip, it may affect sensor function.
Install circlips and flanges from stock system onto both new head pipes
(Figure 5).
Using stock flange nuts, carefully install head pipes onto motorcycle. Do not
tighten at this time.
Use the nut plates and 5/16”x5/8” flange bolts (supplied) to attach the pipes to

Check for good alignment at the seam
Align pipes on motorcycle so the gap between the two muffler bodies is
consistent from front to rear (Figure 7). Tighten the exhaust port flange nuts,
the 5/16”x5/8” flange bolts (supplied) and the 3/8”x3/4” flange bolts (supplied)
attaching the bracket to the frame.
Using the #28 hose clamps (supplied) install the muffler heat shields Beginning
with the D308HC on the front head pipe followed by the D309HC on the rear
head pipe. Screw heads should be accessible for adjustment purposes (Figure 4).
Do not tighten at this time.
Adjust all heat shields for the best alignment at the seam where they meet
(Figure 8) and tighten all the hose clamps.
Feed connector for the rear O2 sensor (Black) through the frame and under the
seat. Re-install battery, plug the sensor into the stock wiring connector.
Feed connector for the front O2 (Gray) sensor through the frame and into the
plastic holder on the frame. Plug the sensor into the stock wiring connector.
Re-tighten floor board mounting bolts on models so equipped.
Be sure to tighten all hardware before starting motorcycle.
After installation and before starting the motorcycle, completely clean pipes
and mufflers with warm soapy water and a clean soft cloth that will not leave a
residue. NOTE: Any residue, oil, or fingerprints will stain the chrome when the
metal heats up.
EXHAUST CARE - HELPFUL HINTS TO AVOID DISCOLORATION OF EXHAUST SYSTEM
1.
When installing a new set of chrome 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 (chrome wax / polish, glass cleaner, alcohol, ammonia,
etc...) before starting the motorcycle.

4.
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.

FUEL MANAGEMENT
GET THE MOST OUT OF YOUR RIDING EXPERIENCE...
AN AFTERMARKET EXHAUST SYSTEM IS ONLY YOUR FIRST STEP, NOW YOU NEED FUEL MANAGEMENT.
MORE POWER : LESS NOISE
NOW YOU NEED FUELPAK.
Your fuel injected Harley-Davidson® is equipped with an ECU (electronic
control unit) that’s programmed to deliver fuel to the motor based on an air/
fuel ratio for a stock air filter and stock exhaust system. When you install a
performance exhaust system, your airflow changes, so you need a
fuel management system that adjusts your air/fuel ratio to match
the changes. That fuel management system is Fuelpak. Fuelpak
adds and takes away fuel, allowing for a more precise range of
refinement in your air/fuel ratio. Get the perfect fuel management
combination with your Vance & Hines exhaust system, get Fuelpak.
