V.A.L.E.™ Assembly Detail
7. Slip S-bend tube of V.A.L.E.™muffler assembly with
barrel clamp pre-installed into head pipe. Use supplied
8 x 30mm flange bolt to loosely attach upper muffler
mount. Use the supplied 11mm spacer between muffler
bracket and frame.
8. Making sure that the V.A.L.E.™assembly is oriented
correctly, securely tighten upper muffler mounting bolt.
9. Securely tighten the 4 (four) 6mm x 14mm hex head
bolts of the V.A.L.E.™assembly.
10. Securely tighten muffler joint clamp and muffler
mounting bolt.
11. Re-inst all side pa nel.
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.
TM
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 - #005-10 038, 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 - #005-10 038, 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.
