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: 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 canister 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.

Two Brothers Racing products are intended for closed course competition purposes only, and therefore are sold

arising from the use of these products or parts.

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 & header.

4. Loosely install the TBR header.

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. Secure muffler assembly to the bike using OEM bolt.

Leave loose for now.

7. Make sure everything is aligned and securely 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.
