Empire Industries Step Pipe Big 3 Power Package Gen 2 – Yamaha YFZ450R (2009+)
The Empire Industries Step Pipe Big 3 Power Package Gen 2 delivers maximum performance for the Yamaha YFZ450R. This complete system combines the Empire Industries Gen 2 Step Pipe performance exhaust, Fuel Customs high-flow intake system, and a Dynojet Power Commander 6 (PC6) to unlock significant horsepower gains and improved throttle response.
The Empire Step Pipe exhaust system features our signature Step Pipe header design which increases exhaust velocity and maximizes engine efficiency across the RPM range. The design works exceptionally well with stock motors and is enhanced with built engines, delivering stronger throttle response, increased mid-range torque, and improved top-end horsepower.
Each Empire Industries exhaust system is handcrafted in the USA using mandrel-bent 304 stainless steel for strength and durability. The TIG-welded aluminum octagon muffler with billet end caps provides aggressive sound, lightweight construction, and easy serviceability.
