SOUL | Porsche 991.2 Carrera X-Pipe Exhaust Revs + Launch

The 991.2 Carrera lineup claimed more performance and efficiency from its turbocharged 3.0-liter engine, but it came at the cost of the distinct character the 911 had been exceptionally known for. The factory PSE does very little to truly deliver the dynamic sound quality that the turbocharged flat-six is capable of, and the turbos naturally suppress the overall volume of the car. Developing a modular rear exhaust solution meant addressing both of those obstacles with the highest priority.

Our non-valved x-pipe tackles these issues right away with an increased 3” tubing diameter and a bespoke design that delivers a smooth, high-pitched tone under load, whereas the factory system’s primary flow path is unrefined without blending of the exhaust. Our chambered x-pipe does not restrict flow during blending, maintaining that full diameter through the tips for optimal velocity which manifests itself with great performance results, whether running with other upgraded components or just the exhaust itself.

Simultaneously, eliminating the secondary flow path from the equation keeps residual flow from bleeding out which maintains a bit more sound volume. Repurposing that secondary flow path into a lengthy Helmholtz chamber reduces low-RPM drone to very reasonable levels and provides a complementary design element to work in concert with the primary x-pipe. Even with upgraded headers or catalytic converters, as featured on our development car, it never reaches a level of aggression that is unsuitable for street use.
