FMF Racing Turbine Core 2.1 Silencer Two Stroke Exhuast
If you are considering purchasing a FMF Turbine Core 2.1 Silencer, it’s likely you’ve recently purchased a new or used two stroke that does not have a spark arrestor. Almost, if not all two stroke dirt bikes do not come with a spark arrested silencer regardless if it’s a motocross bike, enduro or cross country. I’m not sure the reasoning behind this, but it certainly is frustrating if you are an off-road rider.
The FMF Turbine Core 2.1 is spark arrested therefore US Forestry approved which makes you legal to ride off-road and on the trails. Not only is this silencer legal, but it accomplishes it with a design that does not utilize a screen. This is important on two strokes primarily because of mixing oil with the gas also comes through the exhaust and the screen mesh type spark arrestors have the tendency to clog and rob power.
Screen-less design allows the FMF Turbine Core 2.1 to bark without loading up.
FMF’s Turbine Core 2.1 is comprised of an aluminum canister and stainless steel end cap. This makes the upgrade to your bike lighter than stock, along with smoothing out the power curve. The canister itself is a larger diameter, allowing for more exhaust packing and longer service intervals.
I’ve have this silencer on multiple bikes now and it’s always exceeding my expectations. Along with sounding good, I have the peace of mind of being legal AND not worrying about the bike loading up from a screen type spark arrestor.

Some information direct from FMF:
FMF’s Turbine Core 2.1 Silencer is one of the most up to date slip-ons you can get for your 2 stroke exhaust, and it’s complete with convenient spark-arrested performance that proves FMF loves to support 2 strokes and their riders.
Built with an aluminum canister and a stainless mid-pipe and end cap, the 2.1 delivers a smooth power curve throughout the rpms while still coming in at a lighter weight than your stock setup. That’s even considering the larger diameter canister that allows for more packing material and longer service intervals.
But, the 2.1’s main claim to fame is its integrated USFA approved "Turbine Dampening System" spark arrestor. This system prevents all sparks from exiting the exhaust, but it doesn’t choke the flow of exhaust gases like a screen-type arrestor can. It’s also essentially impossible for the Turbine Core to become clogged by residual oil or "spooge" as is common with screen arrestors.
