Description
The SOUL Performance Products Street Headers for Porsche 997 GT3 are engineered to unlock the full potential of the GT3’s high-revving flat-six engine by improving exhaust flow, power delivery, and sound. Designed and manufactured by SOUL Performance Products, these headers replace the restrictive factory units with a high-performance solution built around large-diameter, free-flowing catalytic converters and optimized runner design.
Even with the motorsport heritage of the 997 GT3, factory headers are limited by emissions regulations and production constraints. These limitations affect primary runner length, diameter, and merge efficiency—ultimately restricting performance and sound. SOUL addresses these compromises by redesigning the headers to maximize airflow, delivering noticeable gains in horsepower, throttle response, and exhaust tone.
The result is a sharper, more responsive engine feel with a significantly enhanced exhaust note that properly highlights the iconic flat-six character. The improved flow also amplifies the entire exhaust system downstream, creating a more aggressive yet refined sound profile suitable for both street and track use.
Each set is constructed in-house in the USA using mandrel-bent, thick-wall .065” T304L stainless steel for durability and performance. Precision CNC-machined billet 304L stainless steel head flanges and merge collectors ensure optimal exhaust flow while maintaining structural integrity under extreme conditions. Advanced back-purged TIG welding using high-quality argon gas ensures deep weld penetration and long-term reliability, even under repeated high-heat track use.
Built using precision fixtures to prevent warping during fabrication, these headers are designed for perfect fitment and straightforward installation. Every set undergoes strict quality control and is carefully packaged to arrive in flawless condition. Backed by a lifetime warranty, SOUL Street Headers deliver long-term performance and peace of mind.
