16. Double check your work.
17. Before you run the bike, clean off all ngerprints
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 rst time you
start the bike. This is packing/manufacturing oil
from inside the pipe burning off. Check for gaps or
leaks. If you nd a leak, a little high temperature
silicon sealant should x 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 nish 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 berglass packing inside
is in good condition and not burned out, as exhaust heat inside an empty canister will
deteriorate the carbon ber sleeve.
TBR sells repack kits (Road - #005-10038, Offroad - #005-10038MX) that include
everything you need to easily do it yourself.
Titanium Mufers: For cleaning use a mild water based spray cleaner. Always apply
cleaner or polish with a soft, clean cloth. Always make sure the berglass packing inside
is in good condition and not burned out, as exhaust heat inside an empty canister will
deteriorate the carbon ber sleeve.

Repack all road canisters at the rst signs of packing material deterioration. Part #005-10038
Repack all offroad canisters after every 10 hours of use. Part #005-10038MX
NEVER dyno test your bike with carbon ber 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.
