Two Brothers Racing Honda CBR250R - Manual

1. Make sure the bike is completely cool before starting the
installation. Make sure the bike is secure on a centerstand or
ideally a service lift.
2. Remove OEM muffler by removing 2 bolts.
3. Apply a thin layer of anti-seize to TBR slip tube outlet and
connect to Tarmac muffler using supplied hook springs.
Loosely install barrel clamp onto slip tube inlet.
4. Install TBR slip-on assembly onto stock header and attach
muffler bracket to passenger peg mount using supplied bolt,
washer, and nut. Tighten to snug.
5. Tighten barrel clamp at header connection.
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.

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 finish 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 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 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 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.
