AKRAPOVIC S-PO/TI/8 Exhaust System Slip-On Race Line (Titanium) for PORSCHE 911 GT3 / GT3RS (991.2) 2018-2020

Description Akrapovic Slip-On Race System (S-PO/TI/8) for Porsche 911 GT3 RS / Speedster (OPF)

The Akrapovic Slip-On Race System (S-PO/TI/8) for Porsche 911 GT3 RS / Speedster OPF models is engineered as a high-performance lightweight titanium solution and must be combined with specific mandatory components to ensure correct installation and performance integration.

Mandatory Components:

• Evolution Header Set (E-PO/T/6/1)
• Tail Pipe Set TP-T/S/19 (must be ordered separately)
• When combined with optional carbon fibre diffuser DI-PO/CA/7/G, Tail Pipe Set TP-T/S/17 must be used
• Original Porsche bracket (Porsche p/n: 99111147391) required for installation

The Slip-On Race System must be upgraded into a full Akrapovic Evolution Race Line exhaust system by combining it with the Evolution Header Set (E-PO/T/6) with side mufflers and valves. This configuration enhances performance at higher rpm and delivers a near-linear power curve with optimized torque distribution.

The system incorporates complex titanium components cast in Akrapovic’s in-house titanium foundry and finished with specialized coating technology. Featuring 100 cpsi sports catalytic converters integrated into the exhaust manifold and side mufflers, the Evolution Race Line uses valve functionality and catalytic integration to deliver optimized performance and acoustic output.

The extensive use of lightweight materials results in significant weight reduction. The system delivers a motorsport-oriented sound profile with a deep racing tone under acceleration.

Additional Installation Notes:

• Mandatory Tail Pipe Set TP-T/S/19 must be ordered separately.
• Original Porsche bracket (99111147391) is required for installation.
• When installing Akrapovic aftermarket link pipes with sports catalytic converters or without catalytic converters (for closed track use only), ECU remapping is mandatory.
• For closed-track exhaust configurations, ECU remapping is recommended to prevent potential check engine warning signals.
