IMPORTANT - PLEASE READ CAREFULLY
We recommend that this performance part be installed by a qualied 
motorcycle technician. If you have any doubts as to your ability to install this 
performance part, please consult with your local motorcycle dealer. Read all 
instructions rst before starting installation. Make sure the motorcycle and 
exhaust system are completely cool before starting the installation. Also, 
make sure the bike is secure on a centerstand or ideally a service lift during 
installation. Be sure to save all stock components for possible use later.
1.  Make sure the ATV is completely cool before starting 
the installation. Make sure the bike is secure and is not 
moving during installation. 
2. Remove the stock exhaust system. Save hardware (except 
rear muffler mounting bolt) for later use.
3. Join the V.A.L.E. cap with the end of the M-7 Canister 
using the supplied 6x14mm screws. Be sure to use the 
included split lock washers on all 4 of the screws. Loosely 
tighten all four screws. Keep the screws loose enough so 
that the tube can rotate back and forth inside the V.A.L.E. 
cap.
4. Install Two Brothers titanium headpipe to ATV using stock 
hardware. Snug all fasteners only finger tight for now.
5.  Install entire assembly onto header gently turning it into 
position so that the muffler bracket and the slip on tube 
bracket line up with the appropriate holes. Now slide the 
18mm aluminum spacer behind the canister mounting tab 
and install the 8x85mm screw and Stock nut and tighten 
finger tight.
6. Securely tighten the two 6mm x 14mm cap screws which 
are accessible. This will keep the muffler and s-bend tube 
aligned when the assembly is removed.
7. Carefully remove muffler assembly and s-bend from the 
ATV and fully tighten all four 6mm x 14mm cap screws in an 
“X” pattern. This will insure a good seal and perfect fit.
8. Re-install muffler assembly. Securely tighten all mounting 
hardware.

11. Before you run the atv, 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 atv 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. After 30-60 minutes of use, recheck all 
fasteners for tightness.

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.
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 - #005-10 038, 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 - #005-10 038, 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.
