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 - #005-10038, 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.

Make sure the quad is completely cool before starting 
the installation. Make sure the quad is secure on a 
level surface and the wheels are chocked to prevent 
the quad from rolling. 

Remove the bolts securing the OEM muffler to the 
frame. 

Loosen the OEM clamp connecting the slip tube to 
the header.  This clamp will not be re-used.  

Carefully remove OEM muffler assembly from quad. 

Remove the OEM head pipe and install the new TBR 
head pipe. 

Use the 6 x 14mm bolts and split lock washers to 
loosely attach the X-Lite™ ring to muffler inlet . (See 
V.A.L.E. Assembly Detail below) 

Carefully slide TBR muffler assembly onto the OEM 
header making sure that the TBR slip-tube is fully 
inserted. 

Attach muffler canister to frame using the OEM bolt.  
Leave loose for now. 

Use the OEM bolt to secure the slip-tube to the frame 
and tighten. 

Securely tighten the 4 (four) 6 x 14mm hex head 
bolts of the V.A.L.E. assembly when proper muffler 
alignment is reached. 

Securely tighten the muffler bolt last.

Double check to make sure that all hardware is 
securely tightened. 

Before you run the quad, 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 quad and enjoy. It is normal for 
some white smoke to appear the first time you 
start the quad. 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.
