FSR Technology, the maker of FSR FCU(Fuel Control Unit) for Yamaha FZ150i has released a dyno chart on their FB page about Leo Vince GP Corsa exhaust system that has been fitted to Yamaha FZ150i along with the FSR FCU. It is good to know that the Leo Vince GP Corsa exhaust system do give benefit to the performance to the engine. 

Leo Vince GP Corsa - Aluminium - RM548

From the dyno chart we can see that there is about 2.5hp gain on the mid-RPM range. Even though there are no changes of the horsepower on the top RPM range, that is also good news because this Corsa exhaust does not drop its performance at that range since there are many aftermarket exhaust that is not even better than the stock exhaust at the top RPM range.
