Developed using Akrapovič’s extensive expertise in Porsche exhaust systems, this high-performance upgrade combines advanced materials, precision engineering, and exceptional craftsmanship to transform both the driving experience and vehicle character.
Lightweight Titanium Construction & Carbon-Fibre Tailpipes
Manufactured from high-grade lightweight titanium, this system is built for strength, durability, and weight reduction. Key components, including the exhaust valve housing, are produced in Akrapovič’s in-house titanium foundry.
The system is finished with handcrafted carbon-fibre tailpipes, featuring integrated acoustic reflectors that enhance cabin sound feedback—creating a more immersive driving experience.
Dynamic Sound with Intelligent Valve Control
Equipped with a specially developed control kit, the system actively regulates exhaust valves to deliver the perfect sound profile across all driving modes.
• V6 Models: Crisp, sporty high-frequency tone
• V8 Models: Deep, rich, harmonic exhaust note with strong character under
acceleration
• Zero drone: Optimised for everyday comfort without unwanted cabin noise
Proven Performance Gains & Weight Reduction
Dyno-tested for real-world performance improvements, the Akrapovič Slip-On system delivers:
• +9.7 HP (7.1 kW) at 6,450 RPM
• +11 Nm torque at 5,150 RPM
• Up to 46% weight reduction (V8 models – 8.6 kg lighter)
• 44.5% weight reduction (V6 models – 8.3 kg lighter)
• No ECU remapping required – simple installation with immediate gains
Optional Performance Upgrades
Take performance and sound even further with:
• Akrapovič Evolution Link Pipe Set Titanium (for track
use only)
• Akrapovič Sound Kit – driver-controlled exhaust sound adjustment
Important Installation Notes
• ECE type-approved for vehicles equipped with gasoline
particulate filters
• Adding the Sound Kit or Evolution Link Pipe removes ECE approval
• Required fitting kits:
V8 models: P-MF1051
• Additional fitting kit required when installing with Evolution Link Pipe Set
