Thank you for purchasing your Powder Lite or Full Velocity Muffler from Bikeman Performance Plus. Each lightweight muffler is designed to fit in the stock location on your snowmobile. Simply remove your stock silencer and install your Bikeman muffler. If your muffler came with instructions, please follow them carefully to ensure proper fitment. All Bikeman Performance mufflers are jig-built for consistent and proper fitment. They are also dyno-tested for the best possible power and reliability. Before firing your sled up, make sure the muffler fits correctly and has proper clearance. Most mufflers do not require any fuel changes.

Be sure to consult with us if you find your sled running poorly after installation.

INSTALLATION STEPS:

  1. Simply remove your Side Panel.
  2. Remove stock sensor, springs, and muffler.
  3. Remove the 90-degree rubber damper from the bottom of the stock muffler.
  4. Insert this rubber damper on the BMP Powder Lite Muffler as shown in figure A.
  5. Remove the chaincase bolt closest to the chain adjuster and install the supplied spring tab as shown in figure B.
  6. Insert the BMP muffler into place making sure the rubber damper rests on the chaincase.
  7. Spring BMP muffler into place utilizing 3 springs and the new chaincase mounted tab.

 

**Note: The muffler may take some initial force to push over the external pipe stinger**

E-Tec Muffler Sensor Adapter: Is your E-Tec bogging out on long wide opens pulls since you installed an aftermarket muffler? The problem is how sensitive the E-Tec motor is to heat (applies to 2011-13 models). The aluminum finned design dissipates heat to aid in cooling the sensor. Plus, the simple adapter moves the sensor out of the extreme heat inside the muffler, allowing your machine to hold maximum RPM all the time. This adapter will cause the sled to run leaner. This is necessary for models which lose peak RPM because the sensor reads too hot. We recommend not running this adapter until you notice a problem with your sled. We do recommend purchasing it on 2011-13 models WITHOUT THE UPDATED ECU FLASH in case your sled has a bogging problem.

2014-Up models or models with the 2014-Up ECU flash should not use this sensor adapter as it will seem to make the sled run too cool. Most 2014 models will be fine with no adapter. If you have an issue, Bikeman has a tune for our mufflers.
