The SOUL Competition Headers are a premium performance header upgrade for the Porsche 718 Cayman GT4 RS and 718 Spyder RS. Designed specifically around the GT4 RS / Spyder RS exhaust layout, these headers improve sound, flow, response, and weight compared with the factory header assemblies.
For the GT4 RS and Spyder RS platform, SOUL chose to maximize the header section rather than compromise the design with a catted header solution. These Competition Headers use longer tubing and an expanded merge collector designed to meet the 3-inch flow path of the over-axle pipes. The result is a more efficient, freer-flowing header design that pairs with factory or upgraded over-axle pipes.
As a standalone upgrade, these headers sharpen the car’s sound and response. For a more complete setup, they can be paired with SOUL Sport Cat Over Axle Pipes, SOUL Competition Over Axle Pipes, or a full SOUL exhaust package depending on your sound, emissions, and performance goals.

DasMotoring Notes
These are the right choice if you want to increase sound, response, and exhaust flow from the header section of your GT4 RS or Spyder RS. For a catted performance setup, pair these with SOUL Sport Cat Over Axle Pipes. For maximum sound and flow, pair them with SOUL Competition Over Axle Pipes.
Because these headers move the car further away from the factory exhaust configuration, DasMotoring recommends choosing the rest of the exhaust setup carefully based on your intended use, desired sound level, and local emissions requirements. Emissions legality varies by location and vehicle use, so please confirm your local requirements before ordering.
