ATTENTION! THESE HEADPIPES WILL NOT WORK IN COMBINATION WITH STOCK HARLEY
DAVIDSON MUFFLERS DUE TO RIGHT MUFFLER SLIP DESIGN.
PRIOR TO INSTALLATION, MAKE SURE YOUR STOCK HEADPIPE GASKETS ARE IN GOOD CONDITION.
IF YOU HAVE ANY DOUBTS AS TO THEIR CONDITION, REPLACE THEM.
Read all instructions carefully and completely before installing your new exhaust system!
1. Remove the saddle bags, right side cover, and right front floorboard from the frame.
2. Unplug the O
sensors on the front and rear headpipes from the motorcycle wire harness.

3. Remove the stock exhaust system being careful not to damage the headpipe gaskets. If the headpipe
gaskets are in good condition they do not need to be removed from the cylinders. Remove and save the
flanges, nuts, retaining rings, muffler clamps, muffler mount bolts, crossover bracket bolts, and O
from the stock exhaust. Label the O
headpipe.
4. Remove the stock exhaust mount bracket.
5. Install the supplied headpipe support bracket using the stock nut. On 2017-2020 models route the hydraulic
clutch line behind the bracket. On 2021 models route the clutch cable in front of the bracket. See
FIGURES 1 & 2. Lightly snug the nut but DO NOT TIGHTEN so the bracket can be adjusted. The bracket
should be positioned at a slight angle.
