Description
Unlock the full performance potential of your Porsche 992 GT3 or GT3 RS with the Yonristic VANTA Competition Long-Tube Equal-Length Headers. Purpose-built for Porsche's legendary 4.0L naturally aspirated flat-six, these competition-grade headers are engineered to maximize exhaust scavenging, reduce backpressure, and deliver the crisp, high-revving soundtrack expected from one of the world's greatest performance engines.
The factory header assembly is designed to balance emissions compliance, packaging, and refinement, but its shorter primary runners and restrictive catalytic converters limit the engine's breathing potential. The Yonristic VANTA Long-Tube Header System replaces these restrictions with true equal-length primary tubes that precisely synchronize exhaust pulse timing before merging into a high-efficiency MaxFlow collector. This optimized architecture improves cylinder scavenging, increases exhaust gas velocity, and broadens the engine's power curve from the mid-range to the 9,000 RPM redline.
By improving exhaust pulse evacuation, the engine responds more quickly to throttle input while producing stronger torque through the middle of the rev range and increased horsepower at higher engine speeds. The result is sharper acceleration, improved engine efficiency, and an unmistakable motorsport-inspired flat-six sound that remains crisp, clean, and free from excessive rasp.
Manufactured exclusively from AISI 304 stainless steel, every header is precision CAD-designed using OEM 3D scan data and CNC-machined mounting flanges for exceptional fitment accuracy. Each assembly is back-purged and hand TIG-welded, ensuring smooth internal welds that preserve exhaust flow while delivering long-term durability under extreme track conditions.
To further improve reliability, the headers feature a full integrated thermal heat-shield wrap that helps reduce radiant engine bay temperatures, protects surrounding components, and enhances thermal efficiency during aggressive driving.
Customers can choose between 200-cell HJS high-flow catalytic converters for maximum street performance or a catless competition configuration for dedicated motorsport applications. Both options offer significant horsepower improvements, while an optimized ECU calibration can further increase overall performance.
Designed as a true bolt-on upgrade, the VANTA Long-Tube Headers install directly to the factory cylinder heads and mate with the OEM or compatible aftermarket exhaust systems without cutting or welding.
