1. Make sure the bike is completely cool before starting the
installation. Make sure the bike is secure on center stand
or ideally a service lift.

2. Remove the bolts holding the stock canister onto the

flange. Loosen the hardware that holds the canister to
the passenger footpeg and remove the canister from the
bike.

6. 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.

3. Install the canister onto the end of the stock exhaust
flange (the TBR badge faces to the outside). You’ll have
to hold it in place while you start the OEM bolts through
the flange holes and into the inlet. Go ahead and tighten
evenly and fully. (Use Hi-temp silicone on gasket.)

4. Carefully slide the canister clamp over the canister. (Note:
The stainless steel canister clamp and the name badge
on the canister come from the factory with a clear plastic
protective film. Please remove this film before operation.)
Locate both tabs of the canister clamp on the outside of
the hanger bracket. Use the OEM bolt, washers and nut to
secure it. Leave loose for now.

Care & Cleaning

Care & Cleaning

Keep system free of dirt and moisture. Store in a cool, dry place. Make sure vehicle is completely cool before maintenance.

Polished Aluminum Canisters: Use an aluminum or mag wheel polish to restore the bright finish to factory spec.

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 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 (Road - #005-10038, Offroad - #005-10038MX) that include everything you need to easily do it yourself.

Titanium Mufflers: For cleaning use a mild water based spray cleaner. Always apply cleaner or polish with a soft, clean cloth. 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 (Road - #005-10038, Offroad - #005-10038MX) that include everything you need to easily do it yourself.

Repack all road canisters at the first signs of packing material deterioration. Part #005-10038
Repack all offroad canisters after every 10 hours of use. Part #005-10038MX

NEVER dyno test your bike with carbon fiber 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.
