FMF 043209 PowerBomb Header Pipe — Suzuki LT-Z400 / Kawasaki KFX400 (2003-2014) Performance

FMF 043209 — PowerBomb Performance Header Pipe for Suzuki LT-Z400 & Kawasaki KFX400 — Patented "Bomb" Technology for Massive Power Gains and Improved Sound Management

Unlock the hidden performance potential of your Suzuki LT-Z400 or Kawasaki KFX400 with the FMF 043209 PowerBomb Header. This isn't just a standard replacement pipe; it is a precision-engineered performance upgrade that leverages FMF's patented "Bomb" technology. By strategically placing an expansion chamber at the initial stage of the header pipe, the PowerBomb facilitates the expansion and contraction of exhaust sonics, which results in significantly increased exhaust flow and improved engine efficiency. Riders can expect a noticeable boost in performance—up to 10% more horsepower—making this one of the most effective upgrades for your 400cc sport ATV.

Beyond the impressive power gains, the PowerBomb header acts as a highly efficient "pre-muffler." The chamber design helps manage sound pressure, effectively lowering your overall decibel output without sacrificing flow or performance. Constructed from premium, high-strength stainless steel, this header pipe is built to withstand the extreme heat cycles and vibration of championship-level ATV riding. Whether you are hitting the track or navigating technical trails, the PowerBomb provides the reliable, usable power you need to stay ahead of the pack.

• Patented PowerBomb Module: The iconic "Bomb" chamber at the initial stage of the header pipe increases flow and boosts performance by up to 10% in horsepower.
• Advanced Sonic Management: Acts as a "pre-muffler" by expanding and contracting exhaust sonics, effectively lowering overall decibel output while maintaining high flow.
• High-Flow Engineering: The expansion chamber design optimizes the scavenging effect, resulting in improved throttle response and acceleration throughout the power curve.
• Durable Stainless Steel: Manufactured from high-grade stainless steel to resist corrosion, thermal fatigue, and the rigors of competitive off-road riding.
• Precision Fitment: Designed specifically for the Suzuki LT-Z400 (2003-2014) and Kawasaki KFX400 (2003-2006), ensuring a seamless bolt-on installation.
• Proven FMF Heritage: Engineered and tested by the world’s leading exhaust manufacturer to provide reliable, race-proven performance for your sport ATV.

Moto-House MX Pro Tip:

The PowerBomb header is the perfect companion for an FMF slip-on muffler. Installation Tip: When installing the new header, always use a fresh exhaust port gasket to ensure a perfect seal and prevent air leaks, which can negatively affect your engine's power delivery. Tuning Advice: Because this header significantly changes your engine's volumetric efficiency, it is highly recommended to pair this with a jet kit (for carb models) to optimize your air-fuel ratio and protect your engine from running lean.
