2-IN GTk Active Muffler for Air-Cooled Porsches 911, 914, 964 and Carerra

AKEXH

Product Information

Engineered to deliver the best air-cooled sounds and no drone all in a muffler that lets you choose the loudness.

The GTk Active Muffler Line from Ächtung Kraft is designed to deliver the right sound, performance, no drone and personalized choice in the loudness you want for your Air-Cooled Porsche 911 Flat-Six 911, 914, 964 and Carerra.

The GT/k Active Muffler from Achtung Kraft – the perfect addition to your classic Porsche. This high-performance muffler is designed to optimize your Porsche's performance using the latest active muffler technology, while retaining the classic air-cooled Porsche sound that you know and love. Its active valve system allows you to adjust the exhaust note, giving you a deep, rich tone when closed, and an aggressive race car-inspired sound when opened. It's the ultimate way to enhance your Porsche's performance without sacrificing its iconic sound. Our Active GT/k Muffler offers FOUR distinct sound profiles to ensure that drivers have the flexibility to tailor their vehicle's sound to any occasion, driving style, or personal preference. We have tuned each mode to keep a more mild idle, while unleashing the sounds when the revs climb. With the ability to switch between Touring/Sport (with the silencer insert) or Rebel/Rowdy (no insert), Porsche enthusiasts can enjoy a versatile and dynamic auditory experience, progressively increasing in aggressiveness and loudness, all from a single muffler.

TOURING - CLOSED - with Silencer
The Touring sound profile is tailored for those seeking a refined and sophisticated exhaust note. It provides a mellow and subtle sound, allowing for a comfortable and relaxed driving experience. It is perfect for daily commuting, long highway drives, or occasions when a discreet and elegant exhaust note is desired. Touring mode delivers a sporty exhaust note that is great for everyday drives.

SPORT - OPEN - with Silencer
The Sport sound profile offers a more dynamic and spirited exhaust tone, enhancing the driving experience with a noticeable presence. It provides a deeper and throatier sound, amplifying the engine's performance characteristics when over 2k RPM. Sport mode delivers a satisfying growl and increased volume compared to the Touring mode, ideal for spirited driving on winding roads, or when desiring a more engaging driving experience.

REBEL - CLOSED - NO Silencer
For those seeking a more aggressive and attention-grabbing exhaust note, the Rebel sound profile delivers an assertive and powerful tone. It combines a deep rumble with increased volume, making a bold statement and turning heads wherever you go. Rebel mode is suited for those who want their Porsche to be noticed, and prefer a strong and captivating sound, while still maintaining a refined edge.

ROWDY - OPEN - NO Silencer
The Rowdy sound profile represents the pinnacle of intensity and performance-oriented sound. On throttle, it unleashes an aggressive and thunderous exhaust note that demands attention and announces your arrival. Rowdy mode delivers an exhilarating symphony of sound, providing an experience for those who seek the ultimate in auditory excitement. It is perfect for spirited drives, Rallyes, track days, or anytime you want to showcase the raw sound of your flat-six.

The original exhaust on older 964 models can be restrictive in flow, heavy, and produce a muted sound. Switching to this CARGRAPHIC system unlocks the engine’s full potential: better exhaust flow, sharper throttle response, more pronounced exhaust tone, and improved performance — all while retaining reliability and proper fitment. It’s an ideal upgrade for enthusiasts seeking classic 964 sound and performance without resorting to race-only systems.

About All Silencers / Mufflers

Standard Exhaust Systems – Engineered for Performance, Sound & Longevity

A standard exhaust system is essential for your Porsche’s performance, efficiency, and sound. It controls the flow of exhaust gases from the engine, reduces emissions, manages noise levels, and ensures balanced back pressure for optimal power delivery.

At Design911, we supply standard exhaust systems built from high-grade stainless steel and corrosion-resistant materials. Designed to meet or exceed manufacturer performance standards, these systems deliver the perfect blend of durability, refinement, and performance — ideal for both daily driving and restoration projects.

Each exhaust system is developed to ensure precise fitment, excellent gas flow, and an authentic Porsche exhaust note that retains the car’s original character.

What Do Standard Exhaust Systems Do?

A standard exhaust system performs several vital roles that keep your Porsche running efficiently, cleanly, and safely.

Core Functions:

Directs exhaust gases safely away from the engine.
Reduces emissions through catalytic converters and silencers.
Controls back pressure for balanced performance and fuel efficiency.
Minimises engine noise while preserving Porsche’s signature tone.
Aids temperature regulation and exhaust scavenging.

A properly maintained exhaust system ensures smooth performance, reduced fuel consumption, and compliance with emissions regulations.

Why Do Exhaust Systems Fail?

Exhaust systems are constantly exposed to heat, moisture, and corrosive gases — all of which take a toll over time.

Common Causes of Failure Include:

Corrosion and rust from road salt, condensation, and moisture.
Cracked welds or pipes due to vibration and thermal cycling.
Internal baffle damage causing rattling or loss of silencing effect.
Blocked or leaking joints leading to reduced performance and increased noise.
Burnt-out catalytic converters or mufflers reducing efficiency.

Signs of exhaust failure include loud noises, rattling, exhaust odours, or reduced engine performance — all clear indicators that replacement is required.

Why Replace Standard Exhaust Components?

Replacing a worn or damaged exhaust system restores performance, comfort, and efficiency while maintaining your Porsche’s distinctive exhaust tone.

Key Benefits:

Restores proper exhaust flow and back pressure.
Improves fuel efficiency and power output.
Reduces noise and vibration.
Ensures emissions compliance and MOT readiness.
Built from corrosion-resistant stainless steel for longevity.
Direct-fit compatibility for classic and modern Porsche models.

Upgrading to a high-quality standard exhaust preserves the car’s original performance characteristics while ensuring long-lasting reliability.

Highlights:

Precision-engineered exhaust systems for Porsche vehicles.
Optimised gas flow for power, torque, and efficiency.
Durable stainless-steel construction for corrosion resistance.
Designed for authentic tone and perfect fitment.
Suitable for classic restoration and modern maintenance.
Reliable, quiet, and performance-balanced solutions.
