Porsche 992.2 Carrera GTS / Carrera 4 GTS / Targa 4 GTS SOUL Valved Exhaust System

Product Description

The SOUL Valved Exhaust System is designed specifically for the 992.2 Porsche 911 Carrera GTS T-Hybrid platform, providing a substantial increase in exhaust sound and flow while retaining full integration with Porsche's factory electronic exhaust-valve system.

SOUL replaces the restrictive factory rear exhaust with an enlarged 3-inch valves-open flow path, compared with approximately 2.75 inches from the factory. An integrated high-flow harmonic-dampening resonator controls undesirable frequencies without sacrificing the aggressive character expected when the valves are open.

Rather than replacing Porsche's electronic valve strategy, the SOUL system works directly with the factory exhaust-valve actuators and PSE programming. This preserves the smooth, continuously variable valve operation of the 992.2 GTS while creating a much more noticeable difference between refined valves-closed cruising and aggressive valves-open driving.

Purpose-engineered 3D-printed 316L stainless steel inlet and outlet sections optimize exhaust flow through the system, while .065-inch-wall T304L stainless tubing provides strength and durability for demanding street and track use.

The complete SOUL system weighs approximately 22.15 lbs, compared with approximately 29.1 lbs for the factory components, saving approximately 6.9 lbs / 3.1 kg.

FACTORY ELECTRONIC VALVE INTEGRATION:

The 992.2 Carrera GTS uses electronically controlled exhaust valves rather than the simpler vacuum-operated valves found on earlier Porsche models.

These valves are capable of operating at variable positions, rather than simply switching between fully open and fully closed.

Porsche adjusts valve position according to factors including engine speed, throttle input, drive mode, and vehicle operating conditions.

Even during full-throttle acceleration in Sport mode, the factory programming does not necessarily command the valves to remain 100% open at all times.

SOUL engineered the Valved Exhaust specifically around this behavior.

Rather than creating an abrupt transition between two completely different exhaust paths, the SOUL system is designed to produce a smooth change in sound as the valves progressively move.

VALVES OPEN:

With the exhaust valves open, gases flow through the system's enlarged 3-inch primary exhaust path.

Compared with the approximately 2.75-inch factory architecture, the larger path provides greater flow capacity and substantially more sound.

Expect:

• Significantly increased exhaust volume

• Greater turbocharger presence

• Stronger flat-six engine character

• Deeper and more aggressive exhaust tone

• More mechanical feedback under acceleration

• Increased sound throughout the RPM range

• Reduced exhaust restriction compared with the factory rear system

The valves-open configuration is designed for drivers who want considerably more character from the T-Hybrid powertrain without permanently sacrificing cruising refinement.

VALVES CLOSED:

When the factory valves close, the SOUL system substantially reduces overall exhaust volume.

This provides:

• Refined cold-start behavior

• Lower neighborhood departure volume

• Reduced cabin presence

• Comfortable highway cruising

• Smoother low-load exhaust character

• Significantly more refinement than a permanently open non-valved exhaust

SOUL specifically developed the system to create a meaningful sound difference between valves-open and valves-closed operation.

HIGH-FLOW HARMONIC-DAMPENING RESONATOR:

Rather than relying on a heavily restrictive muffler to control sound, SOUL incorporates an integrated high-flow harmonic-dampening resonator.

The resonator targets undesirable frequencies across the RPM range while maintaining a freer-flowing exhaust path.

This allows the system to produce considerably more volume and character when desired without introducing the persistent cabin resonance commonly associated with aggressive aftermarket exhaust systems.

SOUL reports that undesirable cabin presence is kept to an absolute minimum during cruising.

3D-PRINTED 316L INLETS & OUTLETS:

SOUL uses next-generation metal additive manufacturing for critical sections of the exhaust.

The inlet and outlet transitions are 3D printed from 316L stainless steel.

This manufacturing technique allows SOUL to create complex internal geometries optimized specifically around exhaust flow, rather than being limited to shapes that can easily be produced from conventional bent and welded tubing.

The result is a more controlled transition through the exhaust system while maintaining strength and durability.

3-INCH VS. FACTORY 2.75-INCH FLOW PATH:

The factory valves-open exhaust path measures approximately:

2.75 inches

SOUL increases the primary valves-open path to:

3.0 inches

The larger diameter increases available exhaust-flow capacity while reducing restriction through the rear exhaust.

This becomes increasingly useful as additional modifications—particularly a freer-flowing downpipe—are added to the vehicle.

SOUND CHARACTER:

The 992.2 Carrera GTS has a noticeably different exhaust character from naturally aspirated Porsche GT models.

Its integrated unequal-length turbo manifolds create a rich, deep turbocharged flat-six tone rather than the extremely high-pitched character associated with a GT3.

SOUL developed the system to enhance that natural engine character rather than attempting to artificially make the GTS sound like a naturally aspirated GT car.

Expect:

• Richer exhaust tone

• Deeper low-RPM character

• Increased turbocharged flat-six presence

• Greater volume throughout the rev range

• Significantly more aggressive valves-open operation

• Refined valves-closed cruising

• Smooth changes in volume as the factory valves operate

• Minimal undesirable cabin drone

The final sound level will also depend heavily on the downpipe installed.

WITH FACTORY DOWNPIPE:

The SOUL Valved Exhaust can be installed as a standalone rear exhaust upgrade while retaining the original Porsche downpipe.

This configuration provides:

• Increased exhaust volume

• Stronger flat-six character

• Larger 3-inch valves-open flow path

• Reduced rear-exhaust restriction

• Retention of factory electronic valve control

• Maximum emissions-system retention upstream

This is the more conservative configuration for customers who primarily want improved sound.

WITH SOUL SPORT CAT DOWNPIPE:

The Valved Exhaust is fully compatible with the SOUL Sport Cat Downpipe.

Combining the two creates a substantially more aggressive complete exhaust configuration.

Expect:

• Significantly increased turbocharger sound

• Greater boost and spool volume

• Reduced post-turbine restriction

• Stronger engine character

• Increased overall exhaust flow

• Greater exhaust volume with the valves open

• Continued valves-closed cruising refinement

This combination is also available from SOUL as its complete Valved Exhaust Package.

VALVED EXHAUST VS. PERFORMANCE EXHAUST:

SOUL Valved Exhaust System

• Rear exhaust only

• Retains factory electronic exhaust valves

• 3-inch valves-open flow path

• High-flow harmonic-dampening resonator

• Meaningful quiet and loud operating modes

• Approximately 6.9 lbs lighter than factory

• Compatible with factory or upgraded downpipe

• Best suited to mixed street and performance use

SOUL Performance Exhaust System

• Complete turbo-back system

• Includes Sport Cat Downpipe

• Full 3.5-inch exhaust architecture

• Non-valved

• No quiet mode

• Maximum exhaust flow and volume

• Manufacturer-reported gains exceeding 50 whp and 40 lb-ft on factory ECU software

The Valved Exhaust is the better choice for customers who want significantly more sound while preserving factory-style control over exhaust volume.

WEIGHT SAVINGS:

Factory Rear Exhaust Components:
Approximately 29.1 lbs / 13.2 kg

SOUL Valved Exhaust System:
Approximately 22.15 lbs / 10.0 kg

Approximate Weight Savings:
6.9 lbs / 3.1 kg

This represents approximately a 24% reduction in rear exhaust weight while also increasing the valves-open exhaust diameter and retaining full electronic valve functionality.

BOLT-ON INSTALLATION:

The Valved Exhaust System is designed as a direct replacement for the factory rear exhaust.

SOUL includes:

• High-grade installation hardware

• Required mounting components

• Resonator heat shield

The system is fixture-tested before shipment to ensure consistent fitment.
