Care & Cleaning
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 Muffl ers: Always make sure the fi berglass 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 fi ber muffl ers 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 fi ber.
Aluminum Muffl ers: Use an aluminum or mag wheel polish such as Mother’s to restore
the bright fi nish to factory spec.

10. Making sure that the V.A.L.E. assembly is oriented
correctly, securely tighten upper muffl er mounting bolt.
11. Securely tighten the 4 (four) 6mm x 14mm hex head bolts
of the V.A.L.E. assembly.
12. Securely tighten the lower muffl er mounting bolt.
10. Securely tighten the head pipe bolt.
13. Double check to make sure that all hardware is tightened
14. Before you run the bike, clean off all fi 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 fi rst time you start the bike. This is packing/
manufacturing oil from inside the pipe burning off. Check
for gaps or leaks. If you fi nd a leak, a little high temperature
silicon sealant should fi x it. After 50 to 100 miles, recheck
all fasteners for tightness.
