V.A.L.E.™assembly.
10. Securely tighten the lower muffler mounting bolt.
11. Reinstall side panel.
12. Double check to make sure that all hardware is tightened.
13. 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.
Care & Cleaning
Care & Cleaning
Keep system free of dirt and moisture. Store in a cool, dry place. Make sure vehicle is
completely cool before maintenance.
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.
Clean using a mild water based spray cleaner. Always apply cleaner or polish with a soft,
clean cloth.
Titanium Header System: Polished titanium pipes will experience color shift ranging
from deep blue/purple through amber after a few heat cycles. This is a normal
characteristic of high quality titanium. Clean using a mild water based spray cleaner.
Always apply cleaner or polish with a soft, clean cloth.
Polished Aluminum Canisters: Use an aluminum or mag wheel polish to restore the
bright finish to factory spec.
Brushed Aluminum Canisters: Clean using a mild water based spray cleaner. Always
apply cleaner or polish with a soft, clean cloth.
Carbon Fiber Canisters: Clean using a mild water based spray cleaner. Always apply
cleaner or polish with a soft, clean cloth. 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 (Road - #005-10038, Offroad - #005-10038MX) that include
everything you need to easily do it yourself.
Titanium Mufflers: For cleaning use a mild water based spray cleaner. Always apply
cleaner or polish with a soft, clean cloth. 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 (Road - #005-10038, Offroad - #005-10038MX) that include
everything you need to easily do it yourself.
Repack all road canisters every 3,000 miles. Part #005-10038
Repack all offroad canisters after every 10 hours of use. Part #005-10038MX
NEVER dyno test your bike with carbon fiber or titanium canisters installed - the
intense heat and lack of cooling air can quickly burn through the canister material. Two
Brothers Racing does not provide a warranty for burned canisters.
