Lightweight aluminum construction. Premium stainless steel headers. Aggressive full-system performance.
The Pro-Comp 2-1 Full Performance Exhaust System brings handcrafted American engineering, reduced weight and unmistakable exhaust character to 2022–2026 Indian Chief motorcycles equipped with Thunderstroke engines.
The Toce Pro-Comp 2-1 Full Performance Exhaust System was developed specifically for the modern Indian Chief platform, offering a complete exhaust upgrade for motorcycles equipped with Thunderstroke 111 and 116 engines.
Designed for riders looking beyond factory sound and styling, the Pro-Comp combines performance-focused exhaust routing, aggressive sound and lightweight construction in one application-specific full exhaust system.
Unlike universal muffler assemblies, this system was engineered around the Chief chassis with dedicated mounting components, stainless steel header construction and a distinctive aluminum Pro-Comp muffler.
Every Toce Pro-Comp system is manufactured using premium certified materials and dedicated fabrication processes at our Manchester, Connecticut facility.
The stainless steel header assembly provides durability and corrosion resistance, while the aluminum Pro-Comp canister delivers reduced weight and the aggressive visual character associated with Toce Performance.
Each exhaust is hand-welded and developed for the Chief's chassis and mounting architecture, providing a purpose-built solution rather than an adapted universal exhaust assembly.
The Pro-Comp 2-1 was designed to deliver more than an aggressive exhaust note. Toce's published dyno testing demonstrated an increase of 8 wheel horsepower over the factory exhaust configuration before any factory ECU modifications.
Peak measured output in the documented test reached 101 wheel horsepower and 135 wheel torque, highlighting the performance potential of the Thunderstroke platform with a full 2-1 exhaust system.
Combined with reduced weight and improved exhaust flow characteristics, the result is a performance-focused upgrade engineered to complement the modern Chief's V-twin character.
Dyno figures represent Toce's published test results and are not guaranteed output figures for every motorcycle. Results vary with engine configuration, calibration, supporting modifications and testing conditions.
The modern Indian Chief combines classic American V-twin styling with the Thunderstroke 111 and 116 engine platform.
The Toce Pro-Comp exhaust complements this platform with a performance-focused 2-1 layout, reduced overall weight and a deep, aggressive exhaust note.
Available header, canister and shielding options allow riders to customize the system's appearance while maintaining the same application-specific exhaust design.
The Toce Pro-Comp 2-1 Full Performance Exhaust System is compatible with 2022–2026 Indian Chief motorcycles equipped with Thunderstroke 111 or Thunderstroke 116 engines.
Important for 2025–2026 Models: Newer Indian Chief motorcycles use conical-style exhaust gaskets. This exhaust system requires the earlier flat-style gaskets for proper sealing at the cylinder heads.
During installation on a 2025 or 2026 model, replace the factory conical exhaust gaskets with earlier flat-style exhaust gaskets. Indian OEM part number 5257156 is the recommended reference. Two gaskets are required.
This difference affects the exhaust gasket selection only. It does not prevent installation of the system on compatible 2025 and 2026 Indian Chief motorcycles.
ECU calibration is recommended for optimal throttle response, overall performance and drivability when installing a complete exhaust system on the Thunderstroke platform.
Appropriate calibration can help optimize engine operation to complement the revised exhaust configuration and supporting performance modifications.
Intended for closed-course competition applications where required. Actual performance results may vary depending on ECU calibration, supporting modifications, fuel quality, elevation and motorcycle condition.
