FMF Powerbomb vs Megabomb – Certain bike parts can come with different models and have a list of pros and cons. An example of this is the powerbomb and megabomb. They are a type of pre-muffler if you don’t know what a powerbomb or megabomb is.

The powerbomb helps to lower the bike’s sound output by providing a more sound-absorbing surface area for the sound medium. The megabomb, on the other hand, is a powerbomb with a larger chamber. It produces more low-end to mid-range gains as well as broadening out the mid to top-end power gains over stock.

Both pieces have features that make them stand out, but what makes one better than the other? To answer that, we need to understand what each one offers.

FMF Powerbomb vs Megabomb: Understanding the Parts

What is a FMF Powerbomb

When determining the answer to any comparison, you need to understand what each component offers. The FMF Powerbomb is a four-stroke header that incorporates FMF’s patented PowerBomb module. As stated, it helps to lower the bike’s sound output. Its increased performance and flow are achieved through the expansion and contraction of exhaust sonics.

What is a Megabomb

The megabomb, as stated, is a powerbomb with a larger chamber. Compared to a regular powerbomb, it is used to acoustically deaden sound waves in a pipe using resonance within the larger chamber. How? If you look through the center of the chamber, you’ll find a straight pipe. It has a couple of small (about 1/4″ diameter) holes to allow sound waves to expand out into the chamber.

FMF Powerbomb vs Megabomb: Which is Better?

When you compare the two, the megabomb is basically an improved version of the FMF Powerbomb. It has a larger performance gain than the powerbomb. If you’re looking for a dirt bike with smooth controls and reliable features, consider one with this feature. However, if you want to install a megabomb, make sure it doesn’t compromise the bike in the end.

In comparison, the FFM Powerbomb is said to have a 3-5 HP increase. Unfortunately, this feature is only offered in Titanium so it is more expensive. Depending on what kind of dirt bike you’re looking for, either one of these features can benefit it. However, if you’re still learning about dirt bikes and what fits your needs, it’s best to avoid any modifications and anything related.


The FMF Powerbomb and Megabomb both have their pros and cons. When you compare them, you’re basically comparing a base feature and its improved form. It is not to say that the megabomb is automatically better, but it does have its benefits. If you happen to be a dirt bike enthusiast and want to explore bike parts that can improve your bike, these two features are options to consider.

However, if you aren’t sure about your bike’s exhaust features and have little idea on how to modify your bike, it’s best to get your preferred bike as is and avoid any modifications.
