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 Mufflers: 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 (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 fiber mufflers 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 fiber.
Aluminum Mufflers: Use an aluminum or mag wheel polish such as Mother’s to restore the bright finish to
factory spec.
Installation Instructions

Stainless Steel Full System with S1R Canister
Part # 005-3740105-S1
12. Install supplied 8x75mm socket head cap bolt, spacer, and nut
to mount muffler.
13. Double check to make sure that all hardware is tightened.
14. 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.
