1. Make sure the atv is completely cool before starting
the installation. Make sure the ATV is secure and is
unable to move during installation.
2. Remove the stock slip on (2 bolts at the top of the
mufer and 1 at the header joint)
3. Join the V.A.L.E.™ X-Lite™ ring and slip tube 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 spacers using the supplied 8x25mm ange
bolts between the mufer and frame rail.
5. Tighten the 4 6x14mm V.A.L.E. Cap screws.
6. Before you run the atv, clean off all ngerprints
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 rst 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 nish 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 berglass packing inside
is in good condition and not burned out, as exhaust heat inside an empty canister will
deteriorate the carbon ber sleeve.
TBR sells repack kits (Road - #005-10038, Offroad - #005-10038MX) that include
everything you need to easily do it yourself.
Titanium Mufers: For cleaning use a mild water based spray cleaner. Always apply
cleaner or polish with a soft, clean cloth. Always make sure the berglass packing inside
is in good condition and not burned out, as exhaust heat inside an empty canister will
deteriorate the carbon ber 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 ber 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.
