HMF Exhaust Pipe for Yamaha ATV - Penland Pro Series

Backed by the ATV legend Mike Penland, the Penland Pro Series was developed for serious off road racers and trail riders striving to achieve more low-end torque. The removable Torque Range Modifier (see below) adds a low-to-mid range punch, allowing quads to hook-up better in rough conditions. The exhaust is made of T6061 aluminum and is air-rivoted shut for complete durability.

Improved Performance
Increased Torque:

The Torque Range Modifier adds more bottom-end torque for rough conditions.

4-6 dB Increase:

Depending on the model, you can expect a 4-6 dB increase over stock.

Unrestricted Core:

The Performance Series uses a 2 1/8" non-restrictive core for maximum flow.

An ATV Legend:

Backed by GNCC Champion "Mighty" Mike Penland.

Torque Range Modifier - included with all Penland Pro Series exhaust systems

The Torque Range Modifier (TRM ) is an insert that broadens the available torque range of the machine allowing for better "hook up" in certain conditions. The TRM is not a sound damping device and you should see no difference in speed and power. It cannot be used with a Quiet Core Insert or Spark Arrestor because only one of these can occupy the space in the exhaust at one time.
