Warranty

Two Brothers Racing products are intended for closed course competition purposes only, and therefore are sold “as is”

without warranty. Two Brothers Racing specifically disclaims any warranties of merchantability or fitness 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.

We recommend that this performance part be installed by a qualified

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 first 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.

Installation Instructions

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 right side panel.

3. Remove upper muffler mounting bolt.

4. Remove lower muffler mounting bolt & muffler clamp.

5. Remove OEM muffler assembly.

6. Assemble the V.A.L.E. unit. Use the 4 (four) 6 x 14mm

socket head cap screws and split lock washers to loosely
attach half X-Lite™ ring to muffler inlet. Attach slip tube to
muffler and attach the other half loosely.

7. Slip S-bend tube of V.A.L.E. muffler assembly into head

pipe. Loosely secure the muffler canister to the bike using
the supplied 8x35mm flange bolt and spacer. Lower
mount uses OEM bolt.

8. Making sure that the V.A.L.E. assembly is oriented

correctly, securely tighten lower muffler mounting bolt.

9. Securely tighten the 4 (four) 6 x 14mm socket

head cap screws of the V.A.L.E. assembly.
(See V.A.L.E.™ Assembly Detail)

10.Securely tighten the upper muffler mounting bolt.

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

tightened.

12. Re-install the side panel.

13. 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

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.
