R&D Performance Exhaust Power Collector - Kawasaki SXR 1500
The R&D Exhaust Power Collector was developed to directly replace the low performance O.E.M. 12F Kawasaki 4 into 2 into 1 Exhaust header collector with a modern ÒRacing DesignÓ 4 into 1 Merge Collector. The R&D 4-1 Collector has a much larger area change and volume in the collector over the stock restrictive design. The headers primary tube lengths are changed to allow the header to work harder to better scavenge (evacuate) the cylinders exhaust pressures and gases.
