Scorpion Serket Taper Exhaust – Kawasaki Ninja 400


Scorpion have developed a Euro 4 approved slip-on exhaust system which consists of silencer, T304 stainless steel link pipe and full fitting kit. The dyno developed slip-on system has been specifically suited to the Ninja 400 engine, meaning you can just fit and ride, no remapping is required, giving you better throttle response, an increase in bhp and a deeper sportier exhaust tone.
In addition to the slip-on, technicians have developed an interchangeable de-cat header upgrade kit for tuners looking to enhance the performance of the Ninja 400 further. The kit is constructed from T304 stainless steel and utilises mandrel bent pipework for superior gas flow over the original. (De-cat header kit not approved)

Scorpion exhausts have been helping to win motorsport championships for over 20 years, consistently beating teams heavily supported by rival exhaust manufacturers. Those who follow motorsport, will most likely have seen the Scorpion support team in attendance at a huge range of motorcycle, and four wheel series, often without even knowing it. Their involvement in bike racing has always been strictly for development, not promotional purposes. As Scorpion moves into a new era, the intention is to adopt a higher profile with their motorsport program, providing the most relevant development environment to allow true technology transfer from track to road. In particular they intend to build on successes in the BTCC, Porsche Cup, VW Racing Cup, World Endurance, Time Attack and Superbike; plus off road sport including Rally, MX and Supermoto.
