The SOUL Sport Catalytic Converters are designed for Porsche 997.2 Turbo and Turbo S owners looking for increased exhaust flow, improved throttle response, stronger turbocharger sound, and additional performance while retaining catalytic converters.
The restrictive factory catalyst sections are replaced with freer-flowing HJS catalytic converters integrated into purpose-built T304L stainless steel assemblies. The increased flow allows the twin-turbocharged 3.8L engine to breathe more efficiently while retaining a catted exhaust configuration.
SOUL developed the system specifically to increase performance and sound without triggering a check engine light under normal operating conditions. Turbocharger sound becomes more pronounced, throttle response is improved, and the exhaust gains additional character without requiring replacement of the complete rear exhaust system.
Weight is also reduced. The factory catalytic-converter assemblies weigh approximately 16 lbs, while the SOUL Sport Catalytic Converters weigh approximately 11.6 lbs, saving approximately 4.4 lbs / 2.0 kg.

The factory catalytic converters represent a significant restriction within the 997.2 Turbo exhaust system.
SOUL replaces these components with freer-flowing HJS catalytic converters designed to provide substantially greater exhaust-flow capacity while retaining catalyst functionality.
Reducing restriction immediately downstream of the turbochargers allows exhaust gases to leave the turbine housings more efficiently, helping improve throttle response and allowing more turbocharger sound to come through the exhaust.
Unlike a completely catless configuration, the Sport Catalytic Converters retain dedicated catalyst cores and are designed around improved street usability.
Installing the SOUL Sport Catalytic Converters increases both turbocharger and exhaust presence without creating the same dramatic volume increase associated with a completely catless system.
Expect:
Increased turbocharger sound
Greater exhaust presence under acceleration
Sharper response to throttle inputs
Stronger flat-six character
Additional pops and burbles depending on the vehicle's remaining exhaust configuration and ECU calibration
The final volume depends heavily on the remainder of the exhaust system.
Paired with the factory rear exhaust, the Sport Catalytic Converters provide a relatively restrained increase in character.
Pairing them with the SOUL X-Pipe produces a substantially more aggressive complete exhaust configuration while retaining catalytic converters.
SOUL developed the Sport Catalytic Converters specifically to provide increased exhaust flow without triggering a catalyst-efficiency-related check engine light under normal operating conditions.
The high-quality HJS catalysts retain the functionality required by the vehicle's catalyst-monitoring system while flowing more efficiently than the factory components.
Vehicle condition, oxygen-sensor condition, ECU software, fuel quality, and other modifications can influence diagnostic behavior, so no aftermarket exhaust component should be interpreted as an absolute guarantee against unrelated fault codes.
