SOUL Performance developed a dedicated 987.2 application with properly sized 2-inch runners and optimized collectors to extract maximum power from the 3.4L engine while still producing strong gains on the 2.9L. During Dynojet testing on SOUL’s project Cayman S with PDK, the setup recorded peak gains of 8 whp and 11 ft-lbs of torque at 4,100 RPM. Even greater results can be achieved when paired with a proper tune, as reflected on the dyno chart.
