IMPORTANT - PLEASE READ CAREFULLY

We recommend that this performance exhaust system be
installed by a qualified motorcycle technician. If you have
any doubts as to your ability to install this exhaust system,
please consult with your local motorcycle dealer. Read all
instructions first before starting installation. Make sure the
motorcycle and exhaust system are completely cool before
starting the installation. Also, make sure the bike is secure

6. Before you run the bike, clean off all fingerprints and dirt, as
any oily residue will etch the metal and become somewhat
permanent when the system gets hot. Run the bike and
enjoy. It is normal for some white smoke to appear the first
time you start the bike. This

is packing/manufacturing oil from
inside the pipe burning off. Check for gaps or leaks. If you
find a leak, a little high temperature silicon sealant should fix
it. After 50 to 100 miles, recheck all fasteners for tightness.

installation. Make sure the bike is secure on the sidestand or
ideally a rear service stand.

2. Remove the stock canister at the passenger footpeg bracket
and where it bolts to the end of the exhaust pipe. Remove

the exhaust gasket, you will be reusing this gasket.

3. In order to install your new canister you will have to cut off
most of the cone-shaped section of pipe just past the face of
the flange. A hacksaw with a new blade will work fine. Better
yet, a Sawzall with a new blade works extremely well. This
section of pipe is restrictive to the exhaust flow, hindering
performance and it interferes with the installation of the new
canister. This is perfectly normal for aftermarket flange-on
canisters and it will not affect re-installation of the stock
exhaust should you ever want to bolt the stock canister back
on.

4. Slip the new canister onto the stock pipe flange, re-using the
stock exhaust gasket. Use the 8mm x 20mm bolts and tight­en evenly until the flange face surfaces are mated.

5. Carefully slide the canister clamp over the canister. (Note:

The stainless steel canister clamp and the name badge on
the canister come from the fac­tory with a clear plastic protec­tive film. Please remove this film
before operation.) Using the alu-

minum spacer, place it between
the clamp and the footpeg
bracket. Attach it to the footpeg
bracket using the longer bolt

Care & Cleaning / Warranty

Care & Cleaning

Keep system free of dirt and moisture. Store in a cool, dry place. For cleaning use a
mild spray cleaner. Always apply cleaner or polish with a soft, clean cloth.
Stainless Header System: Polished stainless steel pipes will turn a light golden hue
after a few heat cycles, this is a normal characteristic of high quality stainless steel.
Carbon Fiber & X-Metal Mufflers: X-Metal CF canisters will shift color from their
original silver color to an amber color after a few heat cycles, similar to the way our
stainless steel headers shift color. Always make sure the fiberglass packing inside is
in good condition and not burned out, as exhaust heat inside an empty canister will
deteriorate the Carbon Fiber / X-Metal CF sleeve. TBR sells repack kits (TBR part #
005-10038) that include new rivets and repack material as well as a drill bit (#30),
making it easy to do yourself. Also, NEVER dyno test your bike with carbon fiber muf­flers installed - the intense heat and lack of cooling air can quickly cause the CF
material to burn. Two Brothers Racing does not provide
fiber.
Aluminum Mufflers: Use an aluminum or mag wheel polish such as Mother’s to
restore the bright finish to factory spec.
