The Empire Industries E Series Gen 2 Full Exhaust System is designed specifically for stock Yamaha YFZ450 and YFZ450R engines . This system delivers strong, usable power with improved throttle response and excellent rideability across the entire RPM range.

The E Series Gen 2 exhaust provides better pull off the bottom and mid with stronger power in the upper RPMs than our standard system . Featuring a 16-inch muffler design , it produces a quieter exhaust tone than the Yoshimura full exhaust while still delivering the performance riders expect from Empire Industries.

Constructed from high-quality stainless steel , this system is built for durability and performance. The lightweight aluminum octagon muffler paired with billet aluminum end caps allows for easy service and repacking.

Fuel Controller / Jetting Required

A fuel controller or proper jetting is required when installing this exhaust system.

This exhaust fits both fuel-injected and carbureted models. Proper tuning is necessary to maintain correct air/fuel ratios, ensure engine safety, and allow the engine to fully benefit from the increased exhaust flow and performance gains.

Spark Arrestor & Quiet Core Compatibility

Empire quiet cores and spark arrestors clip directly into the standard billet exhaust tips and can be easily installed or removed.

• Quiet cores and spark arrestors clip into the standard billet tips
