FMF Titanium PowerBomb Header

The redesigned PowerBomb is a four-stroke header that incorporates FMF's patented PowerBomb module at a precise location in the initial stage of the header. By positioning this ""Bomb"" at a key point in the system, increased performance and flow is achieved through the expansion and contraction of exhaust waves as they pass through the system. The result is a flow increase of nearly 10%!

The outer chamber in the PowerBomb allows the air to expand, cool and ramp back up at a higher velocity as it passes through this section. Additionally, the PowerBomb also acts as a pre-muffler of sorts which helps to lower the bike's sound output by providing more sound absorbing surface area within the exhaust.

  • Only fits machines equipped with FMF muffler
  • Fabricated using alloys made to FMF's specifications
  • Pre-muffler function softens exhaust noises without compromising engine power
  • Made in the USA

Product Note: Only fits machines equipped with FMF mufflers.

Questions & Answers

  • Is the ktm oem muffler an fmf on my bike? It's a 2012 xcf 350. Thanks

    By: Matt

    The OEM muffler is a proprietary KTM design that won't work with the FMF PowerBomb header in question. The inlet diameter of the stock 350 XC-F muffler is different than that of any FMF muffler that'll fit your bike. Consequently, you must purchase an FMF muffler in order to fit this, or any other FMF header to your machine. We have a few options available to fit that machine:

    FMF Q4 slip-on exhaust for KTM 350 XC-F

    FMF PowerCore 4 slip-on exhuast for KTM 350 XC-F

    FMF Factory 4.1 slip-on exhaust for KTM 350 XC-F

    With any of those FMF KTM 350 XC-F mufflers, you'd replace the complete exhaust system on your machine with a setup that's lighter, and better-flowing than the stock pipe for the ultimate in power and throttle response!
