FMF Stainless PowerBomb Header — Suzuki DR-Z400 / DR-Z400S / DR-Z400SM (also Kawasaki KLX400R/SR) 2000–2022

Swap in this header alone and feel the difference in the midrange — broader, more usable power exactly where you need it on the track.

Fits: Suzuki DR-Z400 / DR-Z400S / DR-Z400SM (also Kawasaki KLX400R/SR) 2000–2022.

Why riders pick it:

• Stainless steel construction built to handle years of off-road abuse
• Opens up mid-to-top-end power beyond what the stock header allows
• Pairs with any FMF slip-on muffler for a complete system down the road
• Direct bolt-on installation, no tuning required
