3. Remove the mufflers.
4. Remove the two nuts that secure the rear exhaust pipe to the rear cylinder head.

Installation Procedures
NOTE: All fasteners should be loose during the initial steps of the installation to ensure proper fit and location of
the new exhaust system.
1. Optional Step: You may remove the old exhaust gaskets and install new ones (not supplied) or continue to use
the ones you have if they are in good condition.
2. Install the front exhaust pipe by threading on the two nuts that will secure the exhaust flange to the front
cylinder head. Do not tighten nuts! Tip: use masking tape to protect chrome surfaces that may come into
contact with other parts during installation.
3. Install the rear exhaust pipe in the same manner.
4. Loosen the four threaded tabs on the black mounting plate as much as you can without them falling off. With
both pipes in place, take the black mounting plate and slide the threaded tabs into the channels on the back of
the pipes until the holes on the black mounting plate align with the stock holes on the bike frame.
5. Install the two 3/8" bolts through the black mounting plate, 7/8" spacers, and bike frame then, thread on the
two 3/8" nyloc nuts on the inside of the frame.
