At the location where the stock mounting studs were removed (Figure1),
Install bracket (stamped 499-P, supplied) 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).
Apply a small amount of anti-seize compound to the threads of the oxygen
sensors and install them into the new head pipes (Gray lead installed into
the front head pipe and the black lead installed into the rear head pipe).
NOTE: Be careful not to get anti-seize on sensor tip, it may affect sensor
function.
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.
Install circlips and flanges from stock system onto both new head pipes.
For the CVO Models so equipped, it is recommended that the swing arm
bolt chrome cover (right side, with cutout) be removed (Figure 5)

Check for good alignment at the seam
Use the nut plates and 5/16”x5/8” flange bolts (supplied) to attach the pipes
to the bracket (Figure 6). Do not tighten at this time.
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 front oxygen sensor (Gray) through the frame and into
the holder on the frame behind rectifier. Plug the sensor into the stock wiring
connector.
Install a new nylon cable tie (supplied) to hold the wires onto frame in the
original location.
Feed wire for the rear O2 sensor through the frame and under the seat.
Re-install battery, plug the sensor into the stock wiring connector.
Be sure to tighten all hardware before starting 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
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 a soft cloth and cleaning solvent that will leave
no 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.
