Porsche 991.2 Carrera Base / S Without PSE SOUL Valved Exhaust Package

Product Description

The SOUL Valved Exhaust Package is a comprehensive performance solution developed specifically for 2017–2019 Porsche 991.2 Carrera and Carrera S models not equipped with factory Porsche Sport Exhaust / PSE.

Rather than requiring an expensive factory PSE retrofit, SOUL combines high-flow Sport Catalytic Converters, a bespoke X-pipe exhaust, a secondary muffled flow path, and an independent valve-control system to give non-PSE cars a genuine dual-personality exhaust.

With the valves open, the system emphasizes exhaust flow, turbocharger sound, and a smoother, higher-pitched flat-six exhaust note. Close the valves and exhaust is redirected through the secondary X-pipe muffler path, substantially reducing exterior volume and cabin presence for normal street and highway use.

Valve operation can be controlled using the supplied remote system or programmed into compatible in-car HomeLink buttons.

SOUL describes expected package-level gains of approximately 20 horsepower and 20 lb-ft of torque, while the high-flow catalysts and freer-flowing exhaust architecture also increase turbocharger sound and throttle response.

A VALVED EXHAUST SOLUTION FOR NON-PSE CARS

A factory non-PSE 991.2 Carrera does not have the same driver-selectable exhaust functionality as a PSE-equipped car.

Retrofitting the complete Porsche PSE system can require:

• Additional exhaust hardware

• Valve-control components

• Vehicle coding

• Additional installation labor

• Potential bumper or exhaust-interface considerations

SOUL developed this package as a dedicated alternative.

The package gives the non-PSE Carrera a true valved exhaust system while simultaneously upgrading the catalytic converters and rear exhaust.

HIGH-FLOW SPORT CATALYTIC CONVERTERS

The package replaces the restrictive factory catalyst assemblies with SOUL's high-flow Sport Catalytic Converters.

Benefits include:

• Increased exhaust flow

• Improved throttle response

• Increased turbocharger sound

• Greater exhaust presence

• Increased performance potential

• Retained catalytic-converter functionality

SOUL developed the Sport Catalytic Converters to improve flow and sound while avoiding the diagnostic compromises associated with catless bypass pipes.

VALVES OPEN

With the valves open, the system prioritizes exhaust flow and sound.

Expect:

• Significantly increased exhaust volume

• Greater turbocharger whistle

• More turbo spool sound

• Stronger flat-six character

• Increased throttle-related exhaust response

• More pronounced crackles and burbles

• Smoother exhaust-bank blending

• Higher-pitched performance tone

• Greater presence throughout the RPM range

This is the aggressive performance mode of the system.

VALVES CLOSED

Closing the valves redirects exhaust through the package's secondary X-pipe muffler path.

This significantly reduces:

• Exterior exhaust volume

• Cabin presence

• Low-speed sound intensity

• Highway exhaust presence

The engine and turbochargers remain more audible than with the original factory non-PSE exhaust, but the system becomes substantially more civilized than its valves-open configuration.

BESPOKE X-PIPE

SOUL uses an X-pipe architecture to blend the exhaust streams from the opposing cylinder banks.

This helps produce a sound that is:

• Smoother

• More cohesive

• Higher pitched

• More characteristic of Porsche's traditional flat-six exhaust note

This differs from simply increasing exhaust volume with independent left and right pipes.

The X-pipe is an important part of SOUL's attempt to restore some of the naturally aspirated character lost when Porsche transitioned the Carrera platform to turbocharging.

SECONDARY X-PIPE MUFFLER

The quieter flow path incorporates an X-pipe muffler rather than simply closing a valve against the primary exhaust route.

When the valves close, exhaust is redirected through this secondary section to meaningfully reduce sound level.

SOUL developed the system around maintaining a substantial difference between:

Aggressive Valves-Open Operation

and

Civilized Valves-Closed Operation

This makes the package particularly appropriate for cars that see both spirited driving and regular street use.

ANTI-DRONE DEVELOPMENT

The 991.2 Carrera platform can develop undesirable low-frequency cabin resonance when exhaust restriction is reduced.

SOUL therefore incorporated its anti-drone development into this package rather than focusing solely on maximum exterior volume.

The objective is to retain:

• Strong valves-open sound

• Comfortable highway operation

• Reduced undesirable cabin resonance

• A meaningful difference between open and closed modes

The system should still be expected to have greater cabin presence than the original non-PSE exhaust, particularly with the valves open.

REMOTE VALVE CONTROL

Because the vehicle did not leave the factory with PSE, the SOUL package provides its own exhaust-valve control system.

The driver can switch between the exhaust flow paths using a supplied remote.

This allows the exhaust character to be changed independently from the vehicle's factory driving modes.

HOMELINK INTEGRATION

SOUL also allows the valve-control commands to be programmed to compatible HomeLink buttons inside the vehicle.

This can provide a cleaner everyday interface by eliminating the need to keep a separate remote immediately accessible.

The driver can then command the exhaust valves using the integrated HomeLink controls.

PERFORMANCE

SOUL describes the complete package as delivering approximately:

Up to +20 horsepower

and

Up to +20 lb-ft of torque

through the combination of:

• High-flow catalytic converters

• Reduced exhaust restriction

• Large-diameter exhaust tubing

• Freer-flowing X-pipe architecture

These are manufacturer-stated expected package gains rather than a published controlled dyno comparison with detailed baseline conditions.

Actual results will vary depending on vehicle model, fuel, ECU calibration, environmental conditions, and other modifications.

THROTTLE RESPONSE

Reducing exhaust restriction downstream of the turbochargers can improve engine response.

SOUL specifically identifies increased throttle response as part of the package's performance improvement.

The freer-flowing catalytic converters and rear exhaust work together rather than addressing only one restrictive portion of the factory system.

TURBOCHARGER SOUND

Replacing the restrictive factory catalyst assemblies significantly increases the amount of turbocharger sound transmitted through the exhaust.

Expect more:

• Turbo whistle

• Turbo spool

• Turbine sound

• Throttle-related acoustic feedback

• Deceleration character

The result makes the turbocharged nature of the 991.2 Carrera considerably more apparent.

BASE CARRERA TIP FITMENT

Carrera Base models can reuse their original factory exhaust tips.

This makes the Reuse OEM Tips configuration the least expensive option.

Base-model customers can alternatively select SOUL tips if they want to change the exterior appearance.

CARRERA S TIP FITMENT

Carrera S models without PSE cannot use the Reuse OEM Tips configuration.

SOUL specifically requires these vehicles to use compatible SOUL exhaust tips with the Valved Exhaust Package.

Carrera S customers should therefore select:

• Polished Chrome

• Black Chrome

• Carbon Fiber

rather than the OEM-tip option.

POLISHED CHROME TIPS

The Polished Chrome configuration provides a bright, traditional appearance that complements Porsche's factory bright exhaust trim.

Package Price: $6,395.00

BLACK CHROME TIPS

The Black Chrome configuration provides a darker metallic finish for a more understated appearance.

Package Price: $6,595.00

CARBON FIBER TIPS

The Carbon Fiber configuration provides the most motorsport-oriented appearance of the available tip selections.

Package Price: $6,595.00

REUSE OEM TIPS

Carrera Base owners who prefer the original exterior appearance can retain the factory tips.

This also provides the lowest package price.

Package Price: $5,995.00

Carrera S customers should not select this configuration.

CONSTRUCTION

The exhaust components are manufactured from:

Mandrel-bent .065-inch-wall T304L stainless steel

SOUL uses back-purged TIG welding to promote proper weld penetration and protect the interior of the stainless tubing during fabrication.

Each system is built and inspected in-house before shipment.

BOLT-ON FITMENT

SOUL designs and fixture-tests the system around the stock vehicle.

The package is specifically engineered so customers do not need to modify the rear bumper simply to accommodate the exhaust outlets.

That is particularly useful on non-PSE vehicles, where converting to factory PSE hardware can otherwise involve additional fitment considerations.

VALVED PACKAGE VS. FACTORY NON-PSE EXHAUST

Factory Non-PSE Exhaust

• Fixed exhaust behavior

• Quiet factory calibration

• Restrictive factory catalysts

• No driver-controlled exhaust valves

• Factory rear exhaust

SOUL Valved Exhaust Package

• High-flow Sport Catalytic Converters

• Valved rear exhaust

• X-pipe architecture

• Secondary muffled flow path

• Remote valve control

• HomeLink integration capability

• Increased turbocharger sound

• Increased exhaust volume

• Manufacturer-stated gains up to approximately 20 hp / 20 lb-ft

The package essentially adds the sound-control flexibility missing from the factory non-PSE system while also improving exhaust flow.

VALVED PACKAGE VS. FACTORY PSE RETROFIT

The SOUL package is not a replica of Porsche's PSE system.

Instead, it uses its own:

• High-flow catalysts

• X-pipe architecture

• Muffled secondary path

• Valve-control system

SOUL developed this specifically for vehicles that did not originally leave the factory with PSE.

The result is a purpose-built aftermarket solution rather than a conversion using factory PSE components.

EMISSIONS NOTE

The package retains catalytic converters but replaces the original Porsche catalyst assemblies with aftermarket high-flow components.

SOUL's Sport Catalytic Converters are designed to operate without catalyst-related check engine lights under normal conditions, but vehicle condition, calibration, sensor condition, and other modifications can influence diagnostic behavior.

Customers are responsible for determining compliance with applicable emissions laws and regulations for their vehicle and location.
