Yamaha Rhino
Aftermarket Exhaust
At a whopping 22hp in stock form, the power to weight ratio is
pretty sad if you are used to riding an ATV or sand rail. The 660cc engine is
the same one that Yamaha uses in their Grizzly ATV (probably weighs half of a
Rhino).
If you buy a Rhino to cruise the hard pack or maybe just use it
to go camp to camp on the sand dune flats, it will be more than capable. On the
other hand, if you want to really dune with your Rhino, you will be looking for
more power real soon.
Intake, exhaust and jetting are very typical bolt-on type
improvements that have been made to ATVs and motorcycles for years. Since the
Rhino has an ATV engine, it is not surprising that most of the same aftermarket
exhaust manufacturers now have offerings for it. The Rhino has different
power/torque needs and also has a bit more space to work with so some companies
have some unique solutions.
The biggest problem with changing out your OEM exhaust is to
combine strong performance while minimizing noise output. On USFS land and in the state of California, off-road motorcycles are required to
operate at 96db or less when tested with SAE J 1287 standards. Other states like
Oregon (at the Oregon Dunes) have a 93db level. Noise regulation and enforcement
is becoming a popular issue among non-riding residents, state forest personnel
and legislatures looking to constrict the rapidly swelling ATV industry.
Many exhaust manufacturers are focusing resources on producing
quiet exhaust products because they know their survival depends on quiet
technologies that will increase the ever-sought-after horsepower.
For our Rhino Exhaust Buyer's Guide we will focus attention on
the manufacturers that provide the best performance with USFS compliant noise
levels. The list below lists advertised noise level output. From our
experience, the advertised levels for most if not all of these pipes is not
accurate. Do your homework and ask questions before buying. If possible,
listen to different pipes first hand before buying.
Also be aware that to achieve the most power improvements,
aftermarket exhaust requires re-jetting the carburetor and opening up the air
filter and intake.
Yamaha Rhino Exhaust Buyer's Guide:
A stock Rhino comes in at approximately 91db. If you would like
to be quieter than that, you can add a bolt-on
ATV
Silencer from Benz Silent Rider.

Repacking your silencer is important
Loud doesn't equal fast
Many of the exhaust systems built for
Yamaha Rhinos use packing material to reduce noise output. The packing material
does not last forever, and must be replaced.
Repacking your silencer regularly is
important to maintain power and reduce unwanted noise. Don't think that louder
is better for power. Too much air past the holes in the core of the silencer
will make your performance suffer.
