Barrel Header System for Kawasaki Z900

The Header System for Kawasaki Z900 is a plumbing part, not a muffler. It replaces the restrictive catalytic section ahead of your silencer. On the Kawasaki Z900 it is the piece that decides how freely everything downstream can flow.

Fitted on its own it opens up the midrange and sharpens throttle response. Paired with a Barrel canister it is what lets that canister actually do its job, rather than being choked by a restriction further up the system.

Build

• Stainless steel 304 throughout, so it will not rust through a monsoon

Fitment guidance

Listed by Barrel for the Kawasaki Z900. Model years and regional variants do differ, so if you are unsure, send us your registration year and a photo of your current exhaust and we will help you check before you order.

Good to know

• An aftermarket exhaust is louder than stock. Check what your local rules allow.
• Free-flow systems can change fuelling. On some bikes a remap gets the most out of the change.
• We are an authorized Barrel dealer. Every unit is genuine, supplied direct by Barrel.
