Stock Polaris RZR 800 Exhaust
Intake, exhaust and jetting are very typical bolt-on typeimprovements that have been made to ATVs and motorcycles for years. Since thePolaris Ranger RZR has an ATV engine, it is not surprising that most of the sameaftermarket exhaust manufacturers now have offerings for it. The RZR hasdifferent power/torque needs and also has a bit more space to work with so somecompanies have some unique solutions.
The difference with the Polaris Ranger RZR is EFI. An EFI systemwill require a fuel injection adjustment module instead of jetting. Somemanufacturers will offer their own in addition to working with EFI modulecompanies like Dynojet.
The biggest problem with changing out your OEM exhaust is tocombine strong performance while minimizing noise output. On USFS land and inthe state of California, off-road vehicles are required to operate at 96db orless when tested with SAE J 1287 standards. Other states like Oregon (at theOregon Dunes) have a 93db level. Noise regulation and enforcement is becoming apopular issue among non-riding residents, state forest personnel andlegislatures looking to constrict the rapidly swelling ATV industry. Do your part to help keep off-road areas open by selecting an exhaust that meets or exceeds sound level requirements.
Many exhaust manufacturers are focusing resources on producingquiet exhaust products because they know their survival depends on quiettechnologies that will increase the ever-sought-after horsepower. But manyaftermarket exhausts are very loud. Do your homework and ask questions beforebuying.
Since the engine sits sideways, the exhaust exits right near the passenger fender. Not the greatest location. Aftermarket exhaust manufacturers will have to make a similar bend, so don’t expect this to be fixed with a new pipe.
Ask the manufacturer before you buy – “Is your exhaust quiet enough to be legal at 96db or less?”
