Porsche 997 GT3 SOUL Street Headers
POR.997GT3.STH
DEVELOPMENT AND TESTING: Even with the 911 GT3’s elite motorsports pedigree, regulations and external pressures forced compromises to be made. Primary tubing length, runner diameter, and merge collection efficiency are limited even in the most purpose-built of applications, and these compromises come at the cost of sound and power. That’s where we come in. For immediate results, addressing the restrictive factory headers is the place to start, and our upgraded headers are built around large-diameter, free-flowing catalytic converters with optimized cast flanges and runners for maximum gains in power, throttle response, and tone from the GT3’s high-revving flat-six. The resulting change is an amplification of the system rearward, a proper emphasis on the flat-six’s sound as intended, and built to withstand aggressive driving in the most demanding environments. Our billet CNC head flanges allow for not only a more efficient transition from exhaust ports into the runners but add extra strength in a high stress area preventing the chances for any cracking from repeated, hard use during track days.
CONSTRUCTION: Each header set is assembled in house in the USA out of mandrel bent, thick wall .065″” T304L stainless steel. Our billet 304L stainless steel head flanges and merge collector are precision cut on a 5-axis CNC machine for the best possible exhaust flow and strength. Back purged TIG welding (with ARCAL™ Prime argon gas) ensures proper weld penetration and longevity – crucial for durability on the track. We fabricate these headers using thick gauge aluminum fixtures which act as a great heat sink during the welding process and prevent warping not only of our products, but the fixtures themselves to ensure perfect fitment.
BOLT ON AND GO: Every set is rigorously quality-checked prior to shipping and then foam packed to ensure your order arrives in perfect condition.
LIFETIME WARRANTY: Enjoy your SOUL exhaust components with confidence on both the street and track as they are covered by our Lifetime Warranty! Our team will quickly work with you to resolve any issues or answer any questions that you may have.
