FMF is definitely synonymous with off-road race

FMF is definitely synonymous with off-road race and KTM/Husqvarna’s championship-winning endeavours, in particular. We’ve always been a fan with their quieter, Q-series mufflers and also Megabomb headers. The system we consider for our Husqvarna FE 350 test mule is the latest Q4 Hex muffler and S / s Megabomb header.
These components would be the workhorses of FMF’s tire out lineup and built connected with robust stainless-steel (header) along with aircraft-grade aluminum (muffler). Keeping this bike quiet is a priority. FMF claims utmost sound output is 96dB. (We don’t need noise to become fast! ) This bike carries a fairly restrictive emissions system, so, to keep the particular system fueling properly, an exhaust that aligns more with stock can be a wise choice. The Q4 includes a removable spark arrestor (held in by the retainer clip) and calm insert. We kept both in place for this assessment.

Husqvarna FMF Q4 Muffler along with Megabomb Header Review | Rider Analysis
The first step with evaluating an exhaust technique are installation. And there have also been nightmare-ish KTM/Husqvarna steps in the past to get mid-pipes and headers removed/installed. Thankfully, that job is not anymore an issue, as the 2020 bikes allow simple stock-system removal. Likewise, the FMF Megabomb header will come in a header and mid-pipe setup in order to simply thread it with the chassis.

The only slightly complicated portion of swapping the header technique are re-routing the exhaust sensor. The stock header pipe locates the sensor in front of the cylinder, highly visible, and somewhat liable to breakage. The FMF technique smartly tucks the sensor powering the frame, inside the rear from the engine compartment, completely guarded and barely visible. You’ll must loosen the tank and route the sensor cable to the rear of the powerplant. That’s the extent belonging to the install complications.
The FMF unit comes with all the hardware you need to run it except for this frame-mount grommets and collars. You are going to re-use the stock metal collars and rubber parts. These are easy to pop in and out with a dull screwdriver or boxing techinque. Keep their orientation sorted out and slip them back on quite as they come out. It’s simple and should you have leftover parts, try once more.

The whole system lines up well along with the supplied spring retainers really are a welcome part of the total job. They have cool rubber covers offering a nice clean surface. The muffler also stock shares the stock grommets and also collars.

If you beging with the header, move into the mid-pipe and then this muffler, slipping the system together on the way and waiting for everything being connected before you tighten up frame mounts, you should have an easy install. If you ever find the pieces aren’t slipping in, don’t be scared to use a little light spray lube. But keep all the bolts loose until the conclusion.
You’ll notice this isn’t an ultra-light system straightaway. And that’s fine. We’re not overly worried about saving weight; we really just want additional bark in this beast. The quality of your construction is more captivating to us. We weighed complete systems to back and the stock stuff is just about a pound heavier because tested.

The FMF system maintains the lowest overall sound level, however the exhaust tone and crackle are definitely different and much more aggressive than stock. Plus the bike felt like them gained power where most of us wanted it—on the lower-end on the range, especially right away idle. The differences aren’t mind-blowing, but it’s nice to have a tad bit more from the stock powerplant. It’s here we feel the FE lineup needs essentially the most massaging and our exhaust upgrade appeared to start the process well. exhaust muffler 201911ld
