performance part, please consult with your local motorcycle dealer. Read all

Warranty
Two Brothers Racing products are intended for closed course competition purposes only, and therefore are sold “as is”

11. Re-install side panel.
6. Assemble the V.A.L.E.™ unit by slipping the S-bend tube

socket head cap screws and split lock washers to loosely
attach the XLite ™ ring to muffler inlet.

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.

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.
