IMPORTANT - PLEASE READ CAREFULLY
We recommend that this performance part be installed by a qualified

performance part, please consult with your local motorcycle dealer. Read
all instructions first before starting installation. Be sure to save all stock
components for possible use later.
This product was designed for use with no aftermarket or O.E.M. accessories
installed. Any modifications or installation of aftermarket accessories may
cause excessive heat and could result in the damage of the vehicle. Two
Brothers Racing will not be responsible for damaged parts due to heat
1. Make sure the bike is completely cool before starting the
installation. Make sure the bike is secure on a centerstand or
ideally a service lift.
2. Remove right side panel.
3. Remove lower OEM muffler mounting bolt.
4. Remove upper OEM muffler mounting bolt.
5. Remove OEM muffler assembly.
6. Use the 4 (four) 6x20mm Socket Head Cap Screws and split
lock washers to loosely join the slip-tube to the muffler
canister. Do not tighten yet.
7. Insert slip tube of V.A.L.E.™ muffler assembly into OEM
head pipe. Loosely install supplied 8x35mm hanger bracket
bolt and 8x16mm slip-tube bolt.
8. Securely tighten the 4 (four) 6x20mm hex head bolts of the
9. Secure muffler assembly mid-pipe and hanger bracket bolts.
10. Reinstall side panel with original hardware.
11. Double check to make sure that all hardware is tightened
12. 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. Also,
remove any plastic film from the name badge(s). 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.

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 Mufflers:
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 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.
Use an aluminum or mag wheel polish such as Mother’s to restore
the bright finish to factory spec.
