Warning

Special engraved Akrapovic verification code on the muffler inlet cap.

The Akrapovic RACING OPEN line is the highest level of Akrapovic exhaust systems and with hexagonal shaped muffler fits perfectly with the aggressive character of the ‘Z’. The conical tubing with interference crossover tubes between the header tubes work exceptionally well. With the Akrapovic exhaust system you will get massive power boost, more torque, a sportier sound and an even more aggressive top-level look on this muscular roadster. You can choose between classy titanium or carbon-fiber mufflers that stand out through their excellent quality. The systems are available in open version only. Besides great power and torque, you will also save in overall weight, as the Akrapovic system weighs 10.21 kg (RACING) or 11.5 kg (EVOLUTION) less than the stock assembly.

Performance

Measurements of the Akrapovic RACING OPEN & EVOLUTION OPEN system on the Kawasaki Z 1000:

The power curve shows a huge increase over the stock performance figures. It is much more linear, which means the engine is pulling strong and consistently right from the lowest rpm to the highest part of the overrev range. We measured a maximum increased power of 10.0 HP at 10270 rpm.

The same goes for torque, which is also increased through entire rpm range. The drop-outs in the stock curve are filled and like the power curve, there is a major increase from 4000 rpm on.
