The Kawasaki KX250 has undergone some significant engine changes for 2023 and that sparked FMF to make an update to their 4.1 muffler system. The 2023 Kawasaki KX250 engine character has more low end grunt as well as pulling power than last year’s model but it still isn't quite as good as the Yamaha in…

Some muffler questions that get sent to my email inbox usually look like, “which muffler is best for my bike? Is a full system worth the money or can I just get away with purchasing a slip on”? “Is my stock muffler the best muffler option for me”? Instead of trying to keep answering some…
Yes, we know it is tough to get a full muffler system at this point in time as COVID has screwed a lot of inventory up. However, you can find slip on mufflers as FMF has been busy getting product back in stock! We recently tried a dual injector kit on the Yamaha YZ250F and…
I had this initial impression of the Akrapovic Evolution muffler system as I was doing a Racer X Garage Build on the 2022 Honda CR250R. After riding with the system for some time I came away with some notes that you may have not known about the beautiful system for the new generation CRF250R. The…
So the new 2022.5 KTM 450 SX-F Factory Edition has gained seven pounds from the standard 2022 version. If you want to knock off almost two pounds of that with a muffler system and get some added power in the mid range look no further than the FMF 4.1 RCT Full System. Yes, that’s right…
The muffler on the stock 2022 KX250 sounds a little too blown out for me in stock form (even when new). The tone of the muffler is not pleasant to the ear, so I crossed my fingers, called Pro Circuit and picked up a T-6 (stainless system) Muffler System to see if it enhances the…
The 2022 Honda CRF250R is a hot commodity and an aftermarket muffler is even hotter. With COVID-19 wreaking havoc on supply, new muffler systems have been a little slow to get released to the consumer. The Yoshimura RS-12 for the 22 CRF250R should be in stock by the time you read this so let’s compile…
I had the initial impression of the Akrapovic Evolution muffler system as I was doing a MotoConcepts/Bullfrog Spas Honda team test. I noticed that they have been running Akrapovic systems on their bikes, so I asked if I could borrow one to see how it worked. Akrapovic's Evolution line is their full titanium muffler system…
The 2022 Yamaha YZ250 is a hell of a fun bike to ride. Even though I am not a huge two stroke guy, I had a great time riding it and thought it had a better engine character than the previous model. The new intake design really helps smooth the power down low and makes…
When you purchase a 2021 KTM 250 SX-F TLD version the bike comes with a slip on Akrapovic Evolution muffler. However, I know that sometimes, certain machines react better to full systems rather than slip ons, we decided to get the full Evolution system to see how it changes the KTM 250 SX-F’s engine character.…
