American Racing Headers Direct Connection System
2024–2026 Ford Mustang GT 5.0L Coyote (S650)
Big Power Gains with a True Direct-Connect Design
The seventh-generation Mustang GT is a huge leap forward in handling and performance, but the factory exhaust still holds the 5.0L Coyote back. The American Racing Headers (ARH) Direct Connection System for the 2024–2026 Mustang GT 5.0L is designed to unleash that trapped horsepower and torque with gains of up to 30 RWHP, while offering one of the cleanest installs available.
Unlike traditional long systems that require cutting, this Direct Connect setup is engineered specifically to work with stock catback systems with no cutting or welding required. That means you get premium long tube header performance with a more straightforward, factory-friendly connection.
Premium 304 Stainless Steel Construction
Built from start to finish using high-quality 304 stainless steel, this ARH system is engineered for long-term durability, corrosion resistance, and consistent performance. ARH systems are 100% made in the USA and never outsourced, ensuring every component meets strict quality standards.
The headers feature 3/8-inch thick laser-cut flanges for a warp-free seal, along with hand-ported TIG welded inlets for smooth airflow transitions. Optimized primary routing ensures excellent fitment, while the merge collectors with scavenger spikes improve exhaust scavenging for stronger mid-range torque and top-end horsepower.
Primary Size Options for Your Build
This Direct Connection System is available in 1-7/8" primary tube sizes, allowing you to match the system to your performance goals. The 1-7/8" option is better suited for higher horsepower and more aggressive builds.
High-Flow Catted Performance
Catted versions of this system feature severe-duty 300-cell catalytic converters, built for performance applications.
