Akrapovič Slip-On Race Line Adapter Set (SS) Porsche 911 GT3 / GT3 Touring (992.2) 2025+

The Akrapovič Slip-On Race Line Adapter Set (SS) is an essential component for mounting the Slip-On Race Line (Titanium) exhaust on a Porsche 911 GT3 (992.2) with original headers.
Made from high-quality stainless steel and equipped with thermal insulation, this adapter set guarantees optimal performance, a perfect fit, and maximum durability.

Mandatory installation with OEM headers
When the original GT3 headers are retained, this adapter set is mandatory for correct installation of the Akrapovič Slip-On Race Line system.
The carefully designed pipe routing is CFD-optimized (Computational Fluid Dynamics) to ensure smooth gas flow and thus allow the performance and sound of the titanium exhaust system to be fully realized.

High quality and heat protection
The Slip-On Race Line Adapter Set (SS) uses special heat insulation that prevents excessive heat from affecting surrounding components.
This ensures optimal regulation of the exhaust temperature – essential for track use where maximum thermal load occurs.

Performance gain
Tested on the Akrapovič dyno, the system, in combination with the Slip-On Race Line (Titanium), delivers:

• +6.5 kW (8.8 hp) at 2,900 rpm

• +24.1 Nm additional torque at 2,400 rpm
  The gas flow is finely tuned for direct throttle response and improved pulling power across the entire rpm range.

For vehicles without OPF
For GT3 models without an Otto Particulate Filter (OPF), plug inserts and plug nuts from the Akrapovič installation kit must be used to correctly seal the backpressure sensors.
