FMF - Powerbomb Headers Stainless Steel (Yamaha)

FMF - Powerbomb Header

The FMF Powerbomb Header is one of those upgrades that actually lives up to the hype. That distinctive bulge you see — the “Power Bomb” — isn’t just for looks. It’s a tuned expansion chamber that acts like a built-in pre-muffler, increasing exhaust velocity and reducing noise all at once. By expanding and cooling the exhaust gases, then compressing them back through the perforated core, the system smooths out flow, improves throttle response, and adds up to 10% more power across the range.

Built from premium materials and precision-welded, the Powerbomb is tuned for strong bottom-to-mid performance — the range you actually use when accelerating, climbing, or powering through corners. It’s quieter, stronger, and designed with easy oil filter access, so it installs clean and stays practical for everyday riding or racing.

Why We Like It:
You can feel the difference. The bike pulls harder off the bottom, revs smoother through the midrange, and sounds tight without being obnoxious. FMF figured out how to make real gains without extra noise or hassle, and it shows the first time you roll on the throttle.

Why It’ll Work for You:
This header gives you more usable torque and throttle control right where you ride most — in the low and midrange. The Powerbomb’s expansion chamber increases flow and scavenging, meaning quicker response when you crack the throttle and smoother power when you’re working the clutch through tight terrain. It also quiets your exhaust tone naturally, making it perfect for riders who want performance without breaking sound limits.
