4 Stroke Exhaust
Brian in CA
The Fatty! Sometimes a name says it all. Do you remember back in the day when your new exhaust just wouldn't fit. All of the bolts had to barley be put in on one thread and slowly screwed on. No fun! NOT the new fatty from FMF. Bolted right on and sounded crisp. FMF has got me now . Great exhaust!Read All Reviews

The products that come with it are springs and o-rings. The o-rings are a great fit and the springs are nice and tight to make sure your pipe doesnt vibrate off when revving. You get an amazing sticker if youd like to put that on your bike to shower you got an FMF exhaust?Read All Reviews

I purchased the Turbine Core II for a 2023 YZ250X. The fit was perfect and the perfomance is good. I cant really compare the FMF to the stock silencer since I only rode the bike during the breakin period with the stock setup. I bought the FMF for the spark arrestor feature on my way to ride singletrack in Idaho. Rocky Mountain ATV/MC offered the Turbine Core II at a great price. Delivery was fast.Read All Reviews
