Yamaha Rhino Aftermarket Exhaust
At a whopping 22hp in stock form, the power to weight ratio ispretty sad if you are used to riding an ATV or sand rail. The 660cc engine isthe same one that Yamaha uses in their Grizzly ATV (probably weighs half of aRhino). If you buy a Rhino to cruise the hard pack or maybe just use itto go camp to camp on the sand dune flats, it will be more than capable. On theother hand, if you want to really dune with your Rhino, you will be looking formore power real soon. Intake, exhaust and jetting are very typical bolt-on typeimprovements that have been made to ATVs and motorcycles for years. Since theRhino has an ATV engine, it is not surprising that most of the same aftermarketexhaust manufacturers now have offerings for it. The Rhino has differentpower/torque needs and also has a bit more space to work with so some companieshave some unique solutions. The biggest problem with changing out your OEM exhaust is tocombine strong performance while minimizing noise output. On USFS land and in the state of California, off-road motorcycles are required tooperate at 96db or less when tested with SAE J 1287 standards. Other states likeOregon (at the Oregon Dunes) have a 93db level. Noise regulation and enforcementis becoming a popular issue among non-riding residents, state forest personneland 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 onthe manufacturers that provide the best performance with USFS compliant noiselevels. 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 airfilter and intake. Yamaha Rhino Exhaust Buyer’s Guide:A stock Rhino comes in at approximately 91db. If you would liketo be quieter than that, you can add a bolt-on ATVSilencer from Benz Silent Rider.

A Forestry approved spark arrestor is included with each system. Repacking your silencer is importantLoud doesn’t equal fastMany of the exhaust systems built forYamaha Rhinos use packing material to reduce noise output. The packing materialdoes not last forever, and must be replaced. Repacking your silencer regularly isimportant to maintain power and reduce unwanted noise. Don’t think that louderis better for power. Too much air past the holes in the core of the silencerwill make your performance suffer.
