Soul Performance Products - Competition Headers (991 GT3)
Designed to Fit
- 2014 - 2019 Porsche 911 GT3 / GT3 RS (991.1 and 991.2)
SOUL Competition Headers are designed around long tube runners and a billet CNC’ed merge collector to maximize the performance and sound of your GT3.
- Fits all Porsche 991.1 / 991.2 GT3 / GT3 RS models including 911R (2014-2019)
- Max power gains of over 24 whp and 26 ft-lbs of torque (as tested on a GT3 RS)
- All Soul Performance Products are backed by a Lifetime Warranty for both street and track use
DEVELOPMENT AND TESTING: Even a premiere engineering masterpiece like the GT3 comes from Porsche fitted with exhaust manifolds restricted in terms of primary tubing length, runner diameter, and merge collection efficiency due to dense catalytic converters and mass production compromises. By refining the interface between the flange/primary tubes, using smooth radius large diameter bends, and implementing performance oriented collectors with merge spikes, we have been able to achieve increased flow, response, and performance with a more aggressive exhaust note to match. A slip on merge collector was not considered to prevent any chances of exhaust leaks. Instead we focused on designing a high flow collector from CAD to CNC for a no compromise end result. This bespoke billet collector allows for maximized runner length and the elimination of several welds in the interest of durability. Our billet CNC head flanges allow for a more efficient transition from exhaust ports into the runners and adds 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.
POWER: Below are the unedited, straight from the Dyno Jet dyno results as conducted by Power Up Dyno Solutions with before and after runs on the AutoQuest Motorsport 991.2 GT3 RS with no other modifications. Power gains of 20.9 whp and 26.2 ft-lbs of torque come in quickly. Power is increased all throughout the upper power band with an increase of 24.4 whp and 15.3 ft-lbs of torque at 8,400 RPM for a noticeable increase in driving performance. An ECU tune would further take advantage of the increased flow and unlock greater gains.
LIFETIME WARRANTY: Enjoy your Soul exhaust components with confidence on both the street and track as they are covered by a Lifetime Warranty!
