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

Standout Feature: Developed strongly with Husqvarna Factory Race efforts, FMF systems really should be the perfect choice for any people looking for the tire out upgrade on any bike with the lineup.
Husqvarna FMF Q4 Muffler as well as Megabomb Header Review | Riders Analysis
The first phase with evaluating an fatigue method is installation. And there have already been nightmare-ish KTM/Husqvarna steps previously for getting mid-pipes and headers removed/installed. Luckliy, that job is no longer an issue, as the particular 2020 bikes allow effortless stock-system removal. Likewise, the FMF Megabomb header arrive in a header and mid-pipe setup that can assist you simply thread it through the chassis.
The only slightly complicated component to swapping the header strategy is re-routing the exhaust sensor. Your stock header tube discovers the sensor while observing cylinder, highly visible, and somewhat subject to breakage. The FMF program smartly tucks the sensor at the rear of the frame, inside the rear with the engine compartment, completely protected and barely visible. You’ll must loosen the tank plus route the sensor cable towards rear of 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 along with collars. You are gonna re-use the stock metal collars and rubber things. These are easy that could pop in and out which has a dull screwdriver or boxing techinque. Keep their orientation structured and slip them back on just as they come out. It’s simple and when you have leftover parts, try once again.
The whole system lines up well as well as supplied spring retainers certainly are a welcome part of the total job. They have cool rubber covers that include a nice clean complete. The muffler also futures the stock grommets plus collars.
When you beging with the header, leave the mid-pipe and then the retailer's muffler, slipping the system together through trip and waiting for everything to be connected before you shrink frame mounts, you really should have an easy mount. Should you find your pieces aren’t sliding within, don’t be scared to work with a little light spray lube. But keep most of the bolts loose until a final.
You’ll notice this isn’t an ultra-light system straightaway. Along with that’s fine. We’re definitely not overly worried about preserving weight; we really just want more bark in this animal. The quality of their construction is more fascinating to us. We weighed complete systems to back and also the stock stuff is close to a pound heavier whilst tested.
The FMF program maintains the minimum general sound level, even and so the exhaust tone and crackle are definitely different a lot more aggressive than stock. Also , the bike felt like these people gained power where most of us wanted it—on the lower-end to the range, especially right far from idle. The differences aren’t mind-blowing, but it’s nice to have a tad bit more through the stock powerplant. It’s here we appear the FE lineup needs one of the massaging and our exhaust upgrade did actually start the task perfectly.
