Empire Industries E Series Big 3 Power Package Gen 2 – Yamaha YFZ450R (2009+)
The Empire Industries E Series Big 3 Power Package Gen 2 is designed specifically for stock Yamaha YFZ450R engines. This complete performance system combines the Empire Industries E Series Gen 2 performance exhaust, Fuel Customs high-flow intake system, and the industry-leading Vortex X10 ECU to deliver improved throttle response and strong, usable power across the entire RPM range.
The E Series Gen 2 exhaust system is engineered for riders who want excellent rideability while improving overall engine performance. Better pull off the bottom and mid with stronger power in the upper RPM’s than our standard system. With the new 16-inch muffler, it is quieter than the Yoshimura full exhaust while still delivering the performance riders expect from Empire Industries.
Each Empire Industries exhaust system features a durable stainless steel header pipe paired with a lightweight aluminum octagon muffler. Billet aluminum end caps allow for easy service and repacking while maintaining durability and performance.
