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
