Sound, design, and performance have combined to create this stunning exhaust. The Akrapovič sound engineers have produced a rich, harmonic, high-frequency tone from the system in the upper rev range, which perfectly combines with the deep sound in the lower range to provide an aural experience in the cabin with no drone and a sound that lingers long after the throttle is released.
Constructed from lightweight high-grade titanium, with parts made in the in-house foundry to create a perfect fit within the limited space available, the three mufflers – two side and one central – are configured in a unique way, perfectly engineered by the Akrapovič technicians. There is a choice between two different sets of round titanium tailpipes, sandblasted and coated, and available in a natural titanium finish or black. The inner side of the tailpipes features a dynamic relief surface for increased aesthetic value. An engraved logotype adds to the visual presence.
Power gains of +4.8 kW at 3,000 rpm and a torque increase of +15.8 Nm at 2,900 rpm were recorded on the Akrapovič dyno, using a Porsche 718 Cayman GT4 with a stock exhaust system for comparison. This gives the system – which is designed for racing track use only, and is not intended for street use – performance to match its looks and innovative design.
Optional extras are available: there is a Link pipe set in titanium for the Slip-On Line Race (Titanium) upgrade, and a carbon-fibre diffuser, in matte or high gloss, can be added to emphasise the design of the Akrapovič exhaust tailpipes. For more control over the exhaust system's sound, the optional Akrapovič Sound Kit is available to control the exhaust valves at any time and allow the driver to choose the setting preferred.
Fitment notice: A modification of fitting brackets done by Porsche on 718 GT4/Spyder and 718 Cayman/Boxster GTS 4.0 produced approximately after February 2020 was identified. Please turn to your Area sales manager for detailed explanation on differences in order to choose the appropriate exhaust for your car.

Porsche Sport Silencers & Mufflers - Performance Sound & Exhaust Upgrades
Sport Silencers / Mufflers are designed to enhance the sound, performance, and driving character of your Porsche by improving exhaust gas flow and delivering a more engaging exhaust note. Compared to standard exhaust silencers, sports mufflers reduce restriction, sharpen throttle response, and provide a sportier tone that better reflects Porsche’s performance heritage.
Available from Design911, this category includes both genuine Porsche sport exhaust components and high-quality aftermarket performance mufflers, giving owners the choice between factory-engineered authenticity and performance-focused customisation.
What Do Sport Silencers / Mufflers Do?
Sport silencers optimise exhaust flow while enhancing sound quality.
Core Functions:
- Reduce exhaust backpressure for improved engine breathing.
- Enhance throttle response and power delivery.
- Produce a deeper, sportier exhaust note.
- Improve exhaust efficiency and flow dynamics.
- Enhance the overall driving experience.
A well-designed sports muffler balances performance gains with refined sound control.
Why Do Standard Exhaust Silencers Fail or Fall Short?
Standard exhaust mufflers are designed primarily for noise
reduction, emissions compliance, and longevity. Over time, common issues
include:
- Internal corrosion from condensation and heat cycles.
- Restrictive baffling limiting exhaust flow.
- Dull or muted exhaust sound.
- Internal baffle breakdown causing rattles.
- Reduced efficiency when paired with performance upgrades.
As these components age, both performance and sound quality can deteriorate.
Why Upgrade to Sport Silencers / Mufflers?
Sport silencers are engineered to improve both performance and auditory feedback.
Upgrade Benefits:
- Improved exhaust flow and reduced restriction.
- Enhanced exhaust sound without excessive drone.
- Increased driving engagement and responsiveness.
- Available in OEM Porsche or performance aftermarket options.
- Ideal for road, touring, and spirited driving.
Upgrading delivers a more exciting exhaust character while supporting engine efficiency.
Highlights
- Porsche sport silencer and muffler upgrades
- OEM Porsche and premium aftermarket options
- Improved exhaust sound, flow, and performance
- Designed for performance-focused driving
- High-quality materials for durability and reliability
