Removal

!!! WARNING !!! Before working on your machine, make sure it is parked on a level surface with the transmission in park and/or the parking brake engaged. Do not work on any machine with a hot engine or exhaust.  Allow time for all parts to cool in order to reduce the risk of burns.

Blackout Exhausts: Take care not to get grease or oils on the exhaust.  Cleaning our Blackout exhaust with harsh solvents, abrasives, or pressure washers will remove the coating and is not covered under warranty.

1. Loosen the clamp holding the factory silencer to the headpipe.  The clamp is located just behind the shock absorber.(See Figure #1)

Installation

1. Slide the provided #52 T-Bolt Clamp over the inlet of the exhaust.  

2. Slide the inlet of the exhaust over the factory head pipe until the mounting hole on the mounting tab matches with the hole in the frame.  Some pushing and twisting may be necessary to acheive the correct alignment and engagement.  

3. Using the provded (1) M8-1.25x25 Hex Bolt, (1) 3/8" Flat Washer, and one of the original nuts from the factory exhaust mounting hardware loosely secure the HMF silencer to the frame.  (See Figure #3)

5. Check for proper alignment and clearance between the exhaust and other components, then tighting the silencer mounting hardware.  

NOTES: 

Wipe off any fingerprints or markings using a soft cloth and mild detergent such as soap and water or glass cleaner without ammonia.  Once the exhaust heat cycles any oils left on the exhaust may permanently imprint.

If you received a stainless steel exhaust without the Blackout coating it is normal for the pipes to change color as they heat cycle.

The HMF Blackout exhaust will smoke and put out an odor for the first full heat cycle as the coating goes through its final curing process.  It is recommended to allow this process to happen in a well ventilated area.

All systems will produce a smoke out the end cap after a short initial heat cycle, this is the packing material bedding in and is completely normal.
