Why Bolt On a Pipe Guard? Properly designed 2 stroke pipe guards will protect exhaust pipes from power robbing dents and increases horsepower by elevating gas flow temperature. What’s The Best Material To Use? E Line uses a composite of carbon fiber, Kevlar, fiberglass, and high temperature resins in custom molding pipe guards. This combination of materials distributes any impact over a large area to reduce the pipe damage. The lightweight composite has 75% greater tensile strength than aluminum. Aluminum guards or thick wall pipes will not distribute impacts as well and weigh more than E Line’s composite material. Why Custom Mold Each Guard? Just about every exhaust pipe has a different shape. A pipe guard molded to a specific pipe shape eliminates gaps while covering exposed pipe surface. How Do The Guards Mount? The two stroke guards use two stainless steel clamps that wrap around the pipe. The exhaust pipe does not have to be removed for guard installation. What Do The Guards Weigh? The guards weigh between 9 – 20 ounces depending on the model. ***This guard will only fit the bikes listed below that are outfitted with an FMF Factory Fatty Exhaust pipe.
