$399 for a silencer is a lot (non-titanium option is half the price).

What it is

Classic Factory Fatty Pipe.
FMF's newest silencer - the Titanium Powercore 2.1 Silencer.

The Factory Fatty Pipe aesthetically is a departure from FMF’s typical “Gold Series” plated look. It is raw steel and shows off the blue heat marks left from welding which gives it a cool “works” look. The company claims the Fatty broadens and smoothes out the power curve while boosting gains throughout the entire power band, more low-end, more mid, and increased over-rev.

On the back end is the Titanium Powercore 2.1 Silencer. The newer Ti 2.1 silencer is claimed to boast a smooth power curve throughout the RPM range while delivering a crisp bark out of the large diameter Ti canister. Additionally, FMF claims the Ti Powercore 2.1 silencer is lighter than stock while mimicking a four-stroke look in the 4.1 exhaust. If titanium isn’t in the budget, FMF has a similar performing, less expensive aluminum version.

How it works

Broader mid-range power.
Strong top end and overrev.
Almost 1lb. lighter than stock system.
Stylish.
Easy install.

The raw metal of the Factory Fatty does take a little more care since it will rust if left wet. Is it worth it? That’s personal preference, but my opinion is it looks awesome and for me it’s worth the time it takes to wipe it down with a little WD40 after washing. I mentioned the pipe looked awesome, but the silencer is something else. The blue titanium screams sexy and stands out especially well on the white and blue Husky. The titanium is not just for looks though, we put the stocker and the FMF unit on the scale and it’s almost a full pound lighter than the stocker. In addition, installation was easy and only took a few minutes. New o-rings were included and the pipe and silencer lined up perfectly to the mounting points.

One of the first things we noticed about our 2018 Husqvarna TC 250 was it’s limited overrev. It's hard hitting midrange is great on a tight track, but in faster off-road conditions where we typically ride/race the bike it would sign off a little early for my taste. I spoke with the folks at FMF and told them I wanted to smooth the mid-range hit a little and gain more on the top end. They recommended the Fatty pipe with a full length silencer (longer mufflers typically allow bikes to rev further and less quick and in a lot of cases produce more peak horsepower than shorty mufflers) and the results were just what we were looking for. The mid-range power feels more broad and then it pulls strong up into the top end with respectable overrev. The change in power characteristics allows the bike to stay in each gear a little longer and doesn’t need to be shifted quite as much. Jetting remained consistent after installation although we did end up having the carburetor modified by Dick’s Racing. Jetting wasn’t terrible with either pipe, but we couldn’t come up with a setting we were completely happy without Dick’s help. The power delivery with FMF’s exhaust components was a great way to further tweak the Husky to our liking and the combination really shines in the faster GP style events we’ve been frequenting. FMF’s fit and finish has always been good and their latest is no exception.
