10. Install the rear Cobra head pipe / muffler into the rear head using the stock socket head bolts, but
leave the bolts loose to allow the muffler to swing outward away from the swingarm. Be sure the
exhaust gasket is in place. Place the supplied exhaust-mounting bracket onto the existing stud in
the right side frame member, see Figure 4. Align exhaust mounting bracket with rear head pipe so
that two 5/16" flange bolts may be installed but do not tighten at this time. Now install the stock
8 mm nut and two original 8 mm flange bolts into the exhaust bracket but do not tighten at this
time.
11. Install the front headpipe / muffler into the front head using stock socket head bolts, but do not
tighten. Be sure the exhaust gasket is in place. Now, mate the preassembled exhaust valve
solenoid and bracket to the inside of the exhaust- mounting bracket, use two 5/16" flange bolts to
secure the solenoid bracket, exhaust mounting bracket and front headpipe / muffler to each other,
see Figure 4, but do not tighten. Tighten the exhaust mounting bracket's 8 mm nut and 8 mm
bolts to factory specifications. Reconnect the black 3-prong connector and white 2-prong
connector to the exhaust valve solenoid.
12. Make sure the front and rear exhaust assemblies are parallel to each other, then tighten the
following in order: head pipe flanges to the motor (slowly tighten opposing socket head bolt), and
front and rear exhaust assembly to the exhaust bracket.
13. Reinstall the small plastic fairing above the exhaust mounting bracket, and secure with M6 button
head bolt. Reinstall the right side fairing removed in Step 1. Use the steel flanged collar and
rubber grommet removed in Step 2 to space the triangular shaped piece of the fairing (with M109
insignia), away from the frame, press the steel collar back into the large rubber grommet, the larger
face of the steel collar must face inward against the frame, secure the fairing with the stock M6
button head bolt, see Figure 4. Reinstall the seat once all body panels have been secured in
place.
