Product Overview

Manufactured in Slovenia, the Akrapovič Slip-On Race Line (Titanium) exhaust system is designed for the Porsche 911 GT3 and GT3 Touring (992.2). Constructed from high-grade titanium, this system reduces vehicle weight, enhances engine performance, and refines exhaust sound. Engineered for precise fitment, it offers a reliable upgrade for drivers seeking improved vehicle dynamics for both street and track use.

Performance Specifications

This exhaust system improves engine efficiency by optimizing exhaust flow and reducing back pressure, resulting in measurable gains in power and torque. Performance metrics include:

With Adapter Set (SS) and Stock Headers (P-CP034): +17.4 horsepower at 4,650 rpm, +21.2 ft-lb of torque at 4,100 rpm, and a 3.5 kg weight reduction (20.7% lighter than stock).
With Evolution Header Set (Titanium) (E-PO/T/7): +31.6 horsepower at 4,650 rpm, +35.0 ft-lb of torque at 4,650 rpm, and an additional 3.8 kg weight reduction (28% lighter than stock headers).

When installed with stock headers and the Adapter Set, no ECU recalibration is required. Pairing with the Evolution Header Set requires ECU recalibration to ensure proper operation and prevent warning indicators.

Sound Characteristics

The system increases exhaust volume by +4.1 dB, enhancing the sound of the Porsche’s flat-six engine. It delivers a balanced tone at low engine speeds, suitable for regular driving, and a more pronounced sound at higher speeds. Components such as valve housings and muffler collectors, cast in Akrapovič’s foundry, are designed to ensure consistent sound quality and minimize unwanted noise across various driving conditions.

Design and Construction

Crafted to complement the Porsche 911’s design, the exhaust features twin titanium tailpipes with a sandblasted and coated finish. The tailpipes include six imprints on the inner sleeve, reflecting the engine’s six-cylinder configuration. The lightweight titanium construction integrates seamlessly with the vehicle’s underbody, and cast components ensure durability and precision fitment.

Compatibility and Compliance

The Akrapovič Slip-On Race Line (Titanium) is compatible with the Porsche 911 GT3 and GT3 Touring (992.2, 2025 models) and is suitable for street and highway use in the UK. It integrates with the vehicle’s existing systems without requiring ECU recalibration when using stock headers. Designed for closed-course competition, it balances track performance with everyday usability.

Warranty

The product is supported by a 2-year Akrapovič warranty.

Fitment Notes

New Porsche V-clamps may be required to secure link pipes to headers if the original clamps are damaged during stock exhaust removal.

Required and Optional Components

Required: Slip-On Race Line Adapter Set (SS) for installation with stock headers.
Optional: Evolution Header Set (Titanium) for a complete system upgrade.
