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.
Chrome Header System: Chromed header tubing will turn blue close to the exhaust ports, this is normal. To pre­vent corrosion you must keep the header pipes clean.
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.

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 tail section.

3. Remove the stock exhaust system.

4. Install the TBR exhaust system.

5. Place a bead of the hi-temp sealant on the outside edge
of the header that goes into the canister. Slide the TBR
canister onto the end of the header. Wipe off the excess
sealant that will squeeze out.

6. Carefully slide the canister clamp over the canister.
(Note: The stainless steel canister clamp comes from the

factory with a clear plastic protective film. Please remove
this film before operation.) Locate both tabs of the canis-

ter clamp outside of the spacer. Use the supplied bolt and
washer to secure it. Leave loose for now.

7. Make sure everything is aligned and tighten all hardware.

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 your first ride, recheck all fas­teners for tightness.

IMPORTANT - PLEASE READ CAREFULLY
