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 Mufers: 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 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 ber mufers 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 ber.
Aluminum Mufers: Use an aluminum or mag wheel polish such as Mother’s to restore the bright nish to
factory spec.
