FMF Stainless PowerBomb Header — Honda CRF450R / CRF450X 2004–2017

A header built around FMF's resonance chamber design, widening the powerband and setting up whatever slip-on you run behind it.

Fits: Honda CRF450R / CRF450X 2004–2017.

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

⚠️ For closed-course competition / off-road use only — not legal for street use in some states. Confirm your local regulations.
