Read all instructions carefully and completely before installing your new slip-on mufflers
1. Unbolt the headpipe support clamp from the support bracket located midway down the rear headpipe and save
the hardware for reinstallation.
2. Loosen all heatshield clamps for clearance but do not remove the heatshields.
3. Loosen both headpipes at the cylinders. Remove and save the mounting bolts that secure the mufflers to the
mounting bracket/crossover tube.
4. Loosen the stock muffler clamps then rotate the headpipes/mufflers out until the crossover slips disengage.
Remove the stock mufflers from the headpipes. Save the stock clamps because they will be reused.
5. Remove gaskets from stock muffler crossover slips and install them into the supplied slip-on mufflers. If needed,
replacement gaskets may be purchased through your dealer (HD Part #65927-00).
6. Slide the stock clamps over the slip-on mufflers and position them as shown in Figure 1.
7. NOTE: THE MUFFLER WITH THE COBRA LOGO WILL ALWAYS BE THE REAR MUFFLER. Slide the mufflers onto the
headpipes (reverse the order of removal) until the mounting holes align and crossover slips engage. Fasten the
mufflers using the stock mounting bolts in the same manner as stock but do not tighten.

8. Check alignment of front and rear mufflers and make sure they are parallel and crossover slips remain engaged.
Tighten mufflers to mounting bracket. Tighten headpipe flange nuts. Tighten muffler clamps. (NOTE: The muffler
clamps should be flush with the end of the muffler when tightened. See Figure 2. If the muffler clamps are slid
forward past the slots on the slip collar the clamps will not tighten the mufflers properly. Also, make sure the
clamp spacer is not over the slots. The slots need to be covered by the clamp band so that it seals the slots
properly. Rotate the clamp if necessary).
9. Align heatshields and tighten heatshield clamps. Verify that the gap, where the mufflers meet stock heatshields,
is similar to the gap the stock mufflers allotted.
10. Reinstall headpipe support clamp and hardware. Tighten to factory specifications.
11. Tighten any remaining loose hardware to factory specifications.
12. NOTE: The exhaust tips may be loosened and oriented to various positions for different visual effects.
13. IMPORTANT: Before starting your engine remove all fingerprints from all exhaust surfaces. To clean your black
exhaust system use a liquid based soap detergent, such as dishwashing soap applied with a soft cloth and rinse with
clean water. Note: Avoid abrasive cleaning methods such as granular or dry cleansers, simple green, scotch-brite or
steel wool pads. Abrasives may breach the coating and shorten life.
IMPORTANT: To achieve optimum performance from your new mufflers it is suggested that you install a
Cobra Fi2000® Digital Fuel Processor.
