## Description

This Special Chad Wienen Power Kit includes:  FMF 4.1 FULL EXHAUST BLUE CARBON END CAP: The FMF 4.1 Chad Wienen Full Exhaust for the Yamaha YFZ450R incorporates Resonance Chamber Technology, with patented core shape lowers sound level while maintaining maximum power output and canister shape increases internal volume for more sound absorbing material. The chamber is designed to enhance and refine exhaust pressure. The exhaust is tuned with optimized core specifications and comes with the quality, craftsmanship and performance expected from FMF. Meets AMA and FIM sound requirements. VORTEX FUEL AND IGNITION ECU: The Vortex ECU for the YAMAHA YFZ450R is like our CDI and EFI Interceptor rolled into one module. The ECU controls not only Spark timing and Voltage output but also Fuel Metering and other engine management functions. The result is more power, better power, easier starting and ultimately faster lap times. This unit comes pre-programmed with 10 Performance Fuel & Spark timing maps as well as having 3 additional switches for user trimming (adjusting) of Fuel in Lo, Mid and Hi throttle openings. The ECU plugs directly into the bikes standard wiring harness and interfaces with all the standard engine sensors such as ECT (Engine Coolant Temperature), IAT (Intake Air Temperature), MAP (Manifold Absolute Pressure), TPS (Throttle Position Sensor), CPS (Crank Position Sensor) to adjust fuel and spark timing for optimum power delivery in all weather, altitude and load conditions.  Fuel Customs Intake Air Filter: Get amazing power and throttle response with our highly anticipated Yamaha YRZ 450R Intake System. With over a year of R&D put into this system it’s truly a performer.
