Parts List
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
on the sidestand or ideally a rear service stand during
installation. Be sure to save all stock exhaust components
for possible use later.
1. Make sure the bike is completely cool before starting the
installation. Make sure the bike is secure on the sidestand or
ideally a rear service stand.
2. Remove the stock mufflers at the passenger footpeg bracket
and where they slide into the end of each exhaust pipe.
3. Slip the connector pipes onto the stock headers down
beneath the rider footpegs.
4. Place a bead of the hi-temp sealant on the outside edge of
the header that goes into the s-bend. Slide the s-bend onto
the end of the header. Wipe off the excess sealant that will
squeeze out. Repeat on opposite side.
5. Place a bead of the hi-temp sealant on the outside edge of
the s-bend that goes into the canister. Slide the TBR canister
onto the end of the S-bend pipe. Wipe off the excess sealant
that will squeeze out. You can adjust the muffler position by
rotating the slip-on pipe where it meets the header. Repeat
on opposite side.
6. Carefully slide the muffler clamp over the muffler. (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.)
You may need to twist and turn the S-bend a little to get it in
the right place. Locate both tabs of the canister clamp outside of the spacer. Use the 8mm x 75mm hardware to secure
it. Leave loose for now. Repeat on opposite side.
7. Make sure everything is aligned and tighten all hardware.
Affix the connector springs to the muffler. Be sure to check
for proper clearance between the exhaust system and
swingarm.
8. 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.
IMPORTANT - PLEASE READ CAREFULLY

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 a warranty for burned carbon
fiber.
Aluminum Mufflers: Use an aluminum or mag wheel polish such as Mother’s to
restore the bright finish to factory spec.
