The November issue of SnoWest features a product review on the Lightweight Silencer from Starting Line Products. Here's the step-by-step process of how to install it on your machine.
Although installing the Lightweight Silencer isn’t rocket science, if you want a nice clean finish you should take a little extra time on the prep end of things. Simply put, you remove the stock silencer, add some heat tape, and bolt on the SLP can.
The advantages of adding the SLP Lightweight Silencer is outlined in SnoWest Magazine November issue. The highlights include an 8-pound weight reduction and a quicker, cool-sounding snowmobile.
Here’s a quick look at the process on a 2024 Ski-Doo Summit X. The SLP instructions take you through the step-by-step process and everything you need is included in the kit.

Start the process of attaching heat shield tape to everything that is in the muffler cavity, including vent lines, recoil case, chain case rubber cap and vent tube, SHOT housing, and inside of belly pan in the muffler cavity. Put heat sleeves over odometer cable and heat probe cable. (Photo 10)

The weight savings advantage is more that shaving off eight pounds. It makes the snowmobile lighter as you lift it from side to side. This makes the snowmobile handle easier and respond quicker.
The following chart shows the side weight as we lifted the snowmobile off the ground at 6-inch and 12-inch heights.
