This header gains 12.1. The difference is not quality — it is which part of the exhaust each one touches.\u003c\/p\u003e\n\u003cp\u003eA slip-on replaces the last section, after the gas has already passed through a standard header sized for emissions and a catalytic converter that restricts flow by design. A header replaces that restriction. On a 1,043 or 1,099 cc four the result is what the numbers show, and it is why this part costs what it does.\u003c\/p\u003e\n\u003ch2\u003eThree Motorcycles, One Header\u003c\/h2\u003e\n\u003cp\u003eKawasaki uses the same engine architecture across the sport-touring Ninja 1000SX, its 1,099 cc successor the Ninja 1100SX, and the naked Z1100. The header route is shared, so one part covers all three — which is unusual for a component this deep in the engine bay.\u003c\/p\u003e\n\u003ch2\u003eThe Remap Is Mandatory\u003c\/h2\u003e\n\u003cp\u003eAkrapovic states that the engine check light may appear after fitting and that remapping the ECU is mandatory. Removing the catalytic converter changes what the lambda sensors read, and the standard map cannot compensate.\u003c\/p\u003e\n\u003cp\u003eBudget for the remap with the part. Without it the motorcycle will run with a warning light and will not deliver the measured figures.\u003c\/p\u003e\n\u003ch2\u003eWhat You Need Alongside It\u003c\/h2\u003e\n\u003cp\u003eThis header is not a complete exhaust. It requires an Akrapovic slip-on to finish the system — for the Ninja 1000SX and 1100SX that is S-K10SO32-HRT in titanium or S-K10SO32-HRC in carbon, and for the Z1100 it is S-K11SO2-HRC.\u003c\/p\u003e\n\u003ch2\u003eWhat „Optional Header\" Means\u003c\/h2\u003e\n\u003cp\u003eAkrapovic uses the word optional to say that the part is an add-on to a slip-on, not that it is a nice-to-have. Without a matching silencer there is nothing for the header to connect to; with one, the two together form a complete system.\u003c\/p\u003e\n\u003cp\u003eThe naming matters when ordering. An E- part number is always a header and never a full exhaust, and it will never arrive with a silencer in the box.\u003c\/p\u003e\n\u003ch2\u003eFitment and Compatibility\u003c\/h2\u003e\n\u003cp\u003eE-K10R9 covers the Kawasaki Ninja 1000SX from 2020, the Ninja 1100SX from 2025 and the Z1100 from 2025, through model year 2026.
