Empire Industries Stainless Step-Pipe Exhaust System for KTM 690 SMCR / Enduro R – Husqvarna 701 Supermoto – GasGas SM700 (2019–2024)

Empire Industries Stainless Step-Pipe Exhaust System

KTM 690 SMCR / Enduro R – Husqvarna 701 Supermoto – GasGas SM700 (2019–2024)

The Empire Industries Stainless Step-Pipe Exhaust System is engineered to deliver improved performance, aggressive sound, and a distinctive custom appearance for the KTM 690 engine platform.

At the heart of the system is a handcrafted 304 stainless steel step-pipe header, designed to improve exhaust gas velocity and scavenging. This stepped header design increases throttle response, mid-range torque, and top-end horsepower, delivering noticeable performance gains over the factory exhaust.

The system is paired with a 6061 aluminum silencer and CNC billet end caps, making servicing and muffler repacking quick and easy while maintaining long-term durability.

Fuel Controller Required

Empire Industries exhaust systems are designed to flow significantly more air than stock exhausts. This increase in airflow creates a lean condition if additional fuel is not added.

A fuel controller is required to correct the air/fuel ratio, prevent excessive heat, and ensure proper engine performance.

Due to the high-flow design of Empire exhaust systems, generic tunes are not sufficient. Proper tuning is required.

Failure to use a fuel controller will void all warranty.

Carbon Fiber Tip Compatibility

If selecting the Carbon Fiber Exhaust Tip, please review the following information before ordering:

• Quiet Core inserts are NOT compatible with the Carbon Fiber tip.
• If you plan to run a Quiet Core or Spark Arrestor, these inserts must be installed prior to shipping.
• Installing these inserts later will require drilling out the rivets securing the carbon fiber tip to access the muffler core.

To avoid additional installation work, we recommend selecting any desired inserts at the time of purchase.
