HMF Exhaust Pipe for Can Am ATV - Quiet Race Series
The original quiet race exhaust, the HMF Quiet Race Series features an internal mechanical core that controls sound pulses and manages them to a minimum. With race sound regulations becoming stricter, every serious racer needs to consider the dB level of their exhaust. The Quiet Race Series’s core will help you meet sound regulations in most restricted riding areas.
Since the Quiet Race Series was primarily designed to meet sound regulations at the track, the horse power is substantially less than the horse power gain from the Performance or Competition Series. If sound is your top concern, the Quiet Race Series might be the exhaust series that will get you everyting you need.
With the Quiet Race Series' mechanical core, the HMF Quiet Core cannot be used. When compared to the HMF Performance Series with a Quiet Core installed, the Quiet Race Series is a bit quieter with less horse power.
The Quiet Race Series distributes power evenly throughout the entire RPM range.
The Quiet Race Series typically is 2-4 dB over the stock system.
The Quiet Race Series uses a mechanical core to control exhaust pulses and set power levels where they're needed.
