IXIL Decat Collectors Kawasaki Z900 2017-19

Performance-focused decat collectors for the Kawasaki Z900

The Ixil 4-into-1 Decat Collectors for the Kawasaki Z900 are high-flow exhaust components designed to replace the restrictive OEM catalytic converter section. By improving exhaust gas evacuation and reducing system back pressure, these decat collectors can enhance throttle response, reduce overall system weight, and support performance gains when paired with slip-on or full exhaust systems.

This product is non-homologated and not road legal — it removes the catalytic converter and should only be used on track or off-road where regulations permit.
