Firetong Willy Made Full Exhaust Kawasaki Z900 2025–2026 Ø12mm O2 Sensor

The Kawasaki Z900 already has the aggressive stance and four-cylinder character that make it such a distinctive naked bike—but the stock exhaust keeps some of that personality more restrained than many riders would like.

The Firetong Willy Made full exhaust gives the Z900 a deeper, more engaging sound and a cleaner, more purposeful look while preserving the bike’s original character. It’s the kind of upgrade you notice every time you fire it up—and every time you look back at the bike after parking it.

Handcrafted in Brazil by specialized professionals, the system is built fully in stainless steel and developed around the motorcycle’s original parameters for precise fitment on Kawasaki Z900 2025–2026 models equipped with a Ø12 mm O2 sensor.

A removable dB killer is included at no extra cost. The system also comes with an installation guide, warranty certificate and a 12-month manufacturing warranty.
