The FMF Powerbomb and Q4 Muffler are legendary in the exhaust market.

The Powerbomb header promotes better flow by allowing a small expansion of the exhaust gasses improving scavenging. The 'bomb' also acts as a pre-muffler taking the edge off of overall sound levels.

The Q4 muffler employs intricate chambers, baffles and proprietary multistage packing material making it the best performing quiet muffler available with a sound output of 96dB; with most models below 93 dB. It is constructed from aircraft grade aluminum and high strength stainless steel.

Another great combination package - the FMF Powerbomb header and Powercore 4 Muffler.

The Powerbomb header promotes better flow by allowing a small expansion of the exhaust gasses improving scavenging. The 'bomb' also acts as a pre-muffler taking the edge off of overall sound levels.

The PowerCore4 muffler was developed to increase the horsepower and torque throughout the entire power curve and give you a noticeable power increase that is very usable and beneficial, no matter what your riding style or ability is.

Some of the features of the PowerCore 4 include: space age internal packing for maximum packing life; hi-flo modular end cap; internal shape of core uses hi-flo technology; enhanced sonic evacuation provides for higher flow and increased power and removable spark arrestor.

KLR650 '84 - '07

The FMF Powerbomb is a four stroke header pipe unit that has a unique bulge precisely located in the header system. A "pre-muffler" of sorts, the Power Bomb actually lowers sound output because it creates more surface area to absorb the sound medium (exhaust). The surface area of the perforated core lets the sound exit into the absorbing material (steel wool packing) and then allows the air to expand, cool and ramp back up with the higher pressure air. The result? The FMF Powerbomb is instrumental in reducing the decibel level on any four stroke and because of the expansion and contraction on exhaust through the system, the flow has been increased by nearly 10%. That means more power throughout the range.

Features:

  • Tuned for bottom to mid performance
  • Powerbomb headers are the front runner in performance headers
  • Designed for full service access to oil filter
