Instruction Manual >
PRIOR TO INSTALLATION, MAKE SURE YOUR STOCK HEAD PIPE 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. Apply masking tape to any surrounding parts to protect them from getting scratched.
2. For Switchback models, the right side floorboard will need to be removed from the mounts. Also remove
the forward mount bolt and loosen the rearward mount bolt so the mount will swing out of the way for
clearance.
3. Unplug O
2
sensors on front and rear headpipes from motorcycle wire harnesses.
4. 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 and O
2
sensors from the stock exhaust.
5. Remove the stock exhaust mount bracket.
6. Install the supplied exhaust mount bracket using the stock bolts. See
FIGURE 1
. Tighten the bolts to
factory specifications. If applicable, be sure to insert the large spacer between the exhaust mount and the
transmission case as shown in
FIGURE 1
. For Switchback models, also insert 2 of the supplied small
aluminum spacers into the large holes in the exhaust mount bracket as shown in
FIGURE 2
.
