Polaris Ranger RZR
Performance Buyers Guide
Intake, exhaust and jetting are very typical bolt-on type
improvements that have been made to ATVs and motorcycles for years. Since the
Polaris Ranger RZR has an ATV engine, it is not surprising that most of the same
aftermarket exhaust manufacturers now have offerings for it. The RZR has
different power/torque needs and also has a bit more space to work with so some
companies have some unique solutions.
The difference with the Polaris Ranger RZR is EFI. An EFI system
will require a fuel injection adjustment module instead of jetting. Some
exhaust manufacturers will offer their own in addition to working with EFI module
companies like Dynojet.
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. But many
aftermarket exhausts are very loud. Do your homework and ask questions before
The RZR engine sits sideways and behind the seats. The exhaust exits right
near the passenger fender and comes out the center/rear. The air filter for the
RZR is behind the driver's seat and there have been a few problems with dirt
getting past the filter.
