The Kawasaki Z1000 with GPR Powercone Exhaust
For people who want a bit deeper exhaust noise, you can modify the GPR Powercone so they make more noise.
The British made GPR Powercone have a pleasingly raw-edged style, owing to their exposed, hand-finished welding and mini megaphone shape.
They are made from steel and each one has a removable baffle, ensuring compliance with Thai environmental noise regulation. GPR claims a power gain for the Powercone of 4.7 horsepower, without the need to re-map the fueling system.
