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

Care & Cleaning / Warranty

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.

Two Brothers Racing products are intended for closed course competition purposes
only, and therefore are sold “as is” without warranty. Two Brothers Racing specifi cally
disclaims any warranties of merchantability or fi tness for a particular purpose and dis-
claims all responsibility for consequential and incidental damages or any other losses
