FMF is generally synonymous with off-road flashing and KTM/Husqvarna’s championship-winning effort, in particular. We’ve always been a fan on the quieter, Q-series mufflers as well as Megabomb headers. The system we made the decision for our Husqvarna FE 350 test mule is the latest Q4 Hex muffler along with Metal Megabomb header.
These components are the workhorses of FMF’s put on lineup and built associated with robust stainless-steel (header) in addition to aircraft-grade aluminum (muffler). Keeping this bike quiet are sometimes a priority. FMF claims optimum sound output is 96dB. (We don’t have noise being fast! ) This bike features a fairly restrictive emissions system, so, to keep it fueling properly, an exhaust that aligns more with stock is often a wise choice. The Q4 includes a removable spark arrestor (held in through the retainer clip) and hushed insert. We kept constantly in place for this evaluation.

Husqvarna FMF Q4 Muffler plus Megabomb Header Review | Riders Analysis
The first stage with evaluating an fatigue method is installation. And there have been nightmare-ish KTM/Husqvarna steps previously for getting mid-pipes and headers removed/installed. One good thing is, that job is no more an issue, as the specific 2020 bikes allow uncomplicated stock-system removal. Likewise, the FMF Megabomb header can come in a header and mid-pipe setup that can assist you simply thread it through the entire chassis.

The only slightly complicated component to swapping the header technique are re-routing the exhaust sensor. The actual stock header tube finds the sensor while observing cylinder, highly visible, and somewhat vunerable to breakage. The FMF program smartly tucks the sensor driving the frame, inside the rear with all the engine compartment, completely included and barely visible. You’ll have to loosen the tank plus route the sensor cable towards rear with the serp. That’s the extent belonging to the install complications.
The FMF unit comes with the hardware you need to setup it aside from your frame-mount grommets plus collars. You are going to re-use the stock aluminum collars and rubber merchandise. These are easy which will pop in and out with a dull screwdriver or boxing techinque. Keep their orientation organised and slip them back on simillar to they come out. It’s simple and if you have leftover parts, try yet again.

The whole system lines up well along with the supplied spring retainers certainly are a welcome part of the total job. They have cool rubber covers that give a nice clean conclude. The muffler also futures that stock grommets plus collars.

If you beging with the header, move ahead the mid-pipe and then the store's muffler, slipping the system together during the trip and waiting for everything for being connected before you shrink frame mounts, you should really have an easy deploy. Should you find that pieces aren’t sliding with, don’t be scared to apply a little light apply lube. But keep the majority of the bolts loose until the next.
You’ll notice this isn’t the ultra-light system straightaway. Along with that’s fine. We’re definitely not overly worried about keeping weight; we really just want more bark in this animal. The quality of the construction is more intriguing to us. We weighed complete systems to back and also the stock stuff is about a pound heavier whilst tested.

The FMF program maintains the minimum complete sound level, even and so the exhaust tone and crackle are definitely different more aggressive than stock. Plus the bike felt like these people gained power where many of us wanted it—on the lower-end within the range, especially right from the idle. The differences aren’t mind-blowing, but it’s nice to acquire a tad bit more in the stock powerplant. It’s here we appear the FE lineup needs one of the most massaging and our wear upgrade did actually start the method perfectly. exhaust muffler 201911ld
