Installation Instructions
Make sure the UTV is completely cool before starting
the installation. Make sure the UTV is secure on a level
surfance and parking brake set.
Tighten barrel clamp.
Repeat on other side.
Reinstall retaining pins.
Before you run the UTV, 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 UTV and enjoy. It is normal for some white smoke to
appear the first time you start the UTV. This is packing/
manufacturing oil from inside the pipe burning off. Check
for gaps or leaks. After 50 to 100 miles, recheck all
fasteners for tightness.
Remove muffler retaining pins and save for re-use.
Loosen muffler joint clamps, and remove stock muffler.
For ease of installation do one side at a time.
Attach TBR slip tube to TBR muffler using the springs.
Attach barrel clamp to end of slip tube and put a small
amount of anti-seize to the inside of the TBR slip tube
before installation. Install TBR muffler assembly to UTV.

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. This exhaust was not tested with OEM or
aftermarket accessories, damage may occur and is not the responsibility of Two Brothers Racing.
Care & Cleaning
Keep system free of dirt and moisture. Store in a cool, dry place. For cleaning use a mild spray cleaner.
Always apply cleaner or polish with a soft, clean cloth.
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.
Carbon Fiber Mufflers: 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 (TBR part # 005-10038) that include new rivets and repack material as well as a drill bit (#30), making it
easy to do yourself. Also, NEVER dyno test your bike with carbon fiber mufflers installed - the intense heat
and lack of cooling air can quickly cause the CF material to burn. Two Brothers Racing does not provide a
warranty for burned carbon fiber.
Aluminum Mufflers: Use an aluminum or mag wheel polish such as Mother’s to restore the bright finish
to factory spec.
Repack all road canisters every 3,000 miles. Part #005-10038
