Porsche 992.2 GT3 / GT3 Touring SOUL High Pitch Exhaust System

Product Description

The SOUL High Pitch Exhaust System is a complete header-back exhaust system engineered for the Porsche 992 GT3 platform to create a sharper, more exotic, motorsport-derived flat-six soundtrack that becomes increasingly intense as the engine approaches redline.

Rather than simply increasing exhaust volume, SOUL engineered the entire exhaust path around acoustic tuning. The system removes the restrictive factory catalyst assemblies, particulate-filter sections, and oversized factory rear-muffler connection, replacing them with optimized headers, reverse megaphones, dual 2.5-inch exhaust paths, and a single 3-inch final flow path.

Carefully calculated exhaust lengths and merge geometry move the sound toward a higher frequency while maintaining exhaust velocity and flow. At the rear, gases exit through a distinctive 3D-metal-printed single outlet, giving the High Pitch Exhaust a dedicated motorsport appearance rather than using conventional dual bolt-on tips.

The complete system weighs approximately 35.9 lbs, compared with approximately 68.2 lbs for the equivalent factory exhaust components, saving an impressive 32.3 lbs / 14.6 kg.

F1-INSPIRED HIGH-PITCH SOUND:

The High Pitch Exhaust differs fundamentally from a conventional muffler-delete or louder rear exhaust.

SOUL designed the complete system around frequency manipulation.

The goal is not simply maximum volume—it is to move the exhaust note upward in frequency and create a sharper, more exotic sound as engine speed increases.

This is achieved through the combination of:

• Full exhaust-system replacement

• Optimized header geometry

• Reverse megaphones

• Dual 2.5-inch exhaust paths

• Carefully controlled tube lengths

• A merge into a single 3-inch flow path

• Purpose-built single rear outlet

As the GT3's naturally aspirated 4.0-liter engine approaches redline, the system develops an increasingly aggressive and motorsport-inspired tone.

REVERSE MEGAPHONES:

After the headers, exhaust gases enter specially engineered reverse megaphone sections.

Megaphone geometry has long been used in motorsport exhaust systems to manipulate exhaust-wave behavior and acoustic characteristics.

SOUL uses reverse megaphones as part of the High Pitch system's overall acoustic strategy, helping shift the exhaust tone toward the sharper frequency range that distinguishes this exhaust from its other GT3 systems.

DUAL 2.5-INCH TO SINGLE 3-INCH FLOW PATH:

After leaving the headers, the two cylinder banks travel through separate:

2.5-inch exhaust paths

These merge into a single:

3-inch exhaust path

The length of this transition is carefully calculated to tune exhaust frequency while maintaining efficient gas velocity and flow.

This architecture is a major reason the High Pitch Exhaust sounds fundamentally different from SOUL's conventional Performance, Valved, and Race Exhaust configurations.

FACTORY CONNECTION ELIMINATION:

The High Pitch system eliminates the factory GT3's extremely large 7 5/8-inch connection point at the rear muffler assembly.

SOUL also revised the header flange and connection architecture to eliminate the older Porsche-style connection requiring OEM clamps and donut gaskets.

The system instead uses a more efficient V-band connection, providing:

• Cleaner assembly

• Improved exhaust-flow transition

• Easier servicing

• Precise component alignment

• A more purpose-built complete-system architecture

SINGLE 3D-PRINTED OUTLET:

Unlike SOUL's other 992 GT3 exhaust systems, the High Pitch Exhaust does not terminate in conventional interchangeable dual exhaust tips.

Instead, the exhaust exits through a dedicated single 3D-metal-printed outlet.

The outlet is digitally engineered to:

• Integrate cleanly into the GT3 bumper surround

• Provide a motorsport-inspired appearance

• Maintain the system's single 3-inch exhaust architecture

• Minimize heat transfer into nearby bodywork

Because the outlet is an integral component of the High Pitch Exhaust, there are no separate tip style or finish options for this system.

VALVE DELETE MODULES:

The High Pitch Exhaust removes the Porsche factory rear muffler and exhaust valves entirely.

Simply disconnecting the factory electronic valves can create diagnostic faults.

SOUL therefore includes dedicated Valve Delete Modules.

These modules electronically mirror the expected factory valve signals, allowing the ECU to recognize the valve system as operating normally even though the physical valves have been removed.

This allows the High Pitch Exhaust to operate as a permanently unrestricted non-valved system without creating valve-specific check engine lights.

NON-VALVED DESIGN:

The High Pitch Exhaust has:

• No factory rear muffler

• No electronic exhaust valves

• No quiet exhaust path

• No selectable tip configuration

The system operates through its dedicated high-pitch performance path at all times.

Customers seeking factory-style control over exhaust volume should consider SOUL's Valved Exhaust System instead.

SOUND CHARACTER:

Expect:

• Dramatically increased naturally aspirated flat-six sound

• Sharper exhaust tone

• Increasingly exotic character as RPM rises

• Much stronger high-RPM intensity

• More motorsport-oriented exhaust frequencies

• Greater mechanical engine presence

• Immediate response to throttle input

• Distinctive single-outlet sound character

• No factory valve intervention

• No quiet mode

The High Pitch system is specifically intended for customers seeking a more exotic, race-derived sound rather than simply a louder version of the factory exhaust.

WEIGHT SAVINGS:

Comparable Factory Exhaust Components:
Approximately 68.2 lbs / 30.9 kg

SOUL High Pitch Exhaust System:
Approximately 35.9 lbs / 16.3 kg

Weight Savings:
Approximately 32.3 lbs / 14.6 kg

That represents approximately a 47% reduction in exhaust-system weight compared with the factory components being replaced.

EUROPEAN-SPEC VEHICLES:

SOUL specifies that the High Pitch Exhaust also fits European-specification vehicles.

However, European vehicles must be paired with an appropriate:

• OBD solution

or

• ECU calibration

to eliminate resulting emissions-related check engine lights.

This requirement is separate from the included Valve Delete Modules, which address the removal of the factory exhaust valves.

EMISSIONS / COMPETITION USE NOTE:

The SOUL High Pitch Exhaust removes the factory catalytic-converter and particulate-filter assemblies.

This product is not CARB certified and SOUL specifies it for closed-course competition use only.

Removal of factory emissions-control equipment may violate regulations governing vehicles operated on public roads.

Customers are responsible for determining compliance with all applicable federal, state, local, and international regulations before installation or use.
