Warranty Information
Two Brothers Racing products are intended for closed course competition purposes only, and therefore are sold

for a particular purpose and disclaims all responsibility for consequential and incidental damages or any other
losses arising from the use of these products or parts. Not tested for use with OEM or aftermarket accessories.

installation. Make sure the bike is secure on a center stand
or ideally a service lift.
2. Remove OEM mufer by removing 2 bolts.

using OEM bolt and nut.
4. Apply a thin layer of anti-seize to mufer inlet. Attach mufer
to TBR slip system using the supplied hook springs.
5. Install barrel clamp onto slip tube inlet and place into position
on motorcycle.
6. Mount mufer to mounting bracket using supplied hardware.
Spacer goes between mufer bracket and mounting bracket.
7. Check for clearance and alignment, then double check
tightness of all hardware.
8. Before you run the bike, clean off all 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 rst time
you start the bike. This is packing/manufacturing oil from
inside the pipe burning off. Check for gaps or leaks. If you
nd a leak, a little high temperature silicon sealant should x
it. After 50 to 100 miles, recheck all fasteners for tightness.
Care & Cleaning / Warranty Information
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 nish 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 berglass packing
inside is in good condition and not burned out, as exhaust heat inside an empty canister
will deteriorate the carbon ber sleeve.
TBR sells repack kits (Road - #005-10038, Offroad - #005-10038MX) that include
everything you need to easily do it yourself.
Titanium Mufers: For cleaning use a mild water based spray cleaner. Always apply
cleaner or polish with a soft, clean cloth. 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 ber 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 ber 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.
