The Akrapovic S-PO/TI/8-TP Slip-On Race Line delivers a complete titanium muffler and tail pipe package engineered exclusively for the 2018 and 2019 Porsche 911 GT3 (991.2) and the 2019 Porsche 911 Speedster. The S-PO/TI/8-TP replaces the factory muffler assembly with a full titanium structure that trims 9.9 kg from the rear of the car while adding 5 kW and 12 Nm of measurable power.

Installation is a direct slip-on connection requiring no cutting, welding or permanent modification to the vehicle.

Frequently Asked Questions
Does the S-PO/TI/8-TP fit the 2018 Porsche 911 GT3 RS (991.2)?The S-PO/TI/8-TP is specifically designed for the 911 GT3 (991.2). Consult Akrapovic directly to confirm fitment for the GT3 RS variant, which may require a different part number.
Are the tail pipes included or do I need to buy them separately?The titanium tail pipe set with carbon fiber endcaps is included with the S-PO/TI/8-TP. No separate tail pipe purchase is required, unlike the base S-PO/TI/8 variant.
Will the S-PO/TI/8-TP fit the 2019 Porsche 911 Speedster?Yes. The 2019 Porsche 911 Speedster uses the same 991.2 platform and 4.0-liter flat-six as the GT3, making it a confirmed fitment for the S-PO/TI/8-TP.
Does this exhaust require an ECU tune?An ECU remap is not strictly required for basic installation, but Akrapovic recommends ECU recalibration to fully realize the documented power gains of +5 kW and +12 Nm.
Is the S-PO/TI/8-TP street legal?The S-PO/TI/8-TP is a Race Line system designed for closed-course and motorsport use. It is not intended for unrestricted street operation. Verify local regulations before use on public roads.
How much weight does the S-PO/TI/8-TP remove?The complete S-PO/TI/8-TP system weighs 7.3 kg versus the factory 17.2 kg muffler assembly, a reduction of 9.9 kg concentrated at the rear of the vehicle.
Will installation of the S-PO/TI/8-TP void my Porsche warranty?Aftermarket exhaust modifications may affect portions of the Porsche factory warranty. Consult your authorized Porsche dealer and review the Magnuson-Moss Warranty Act for guidance specific to your situation.
What does the Akrapovic Race Line exhaust sound like on the 991.2 GT3?The S-PO/TI/8-TP produces a deep, full-bodied exhaust note at idle that escalates to a high-pitched flat-six howl above 6,000 rpm, louder and more aggressive than the OEM system while retaining the character of the naturally aspirated engine.
Installation Instructions
- Allow the vehicle to cool completely before beginning work. The exhaust system reaches extreme temperatures during operation.
- Raise and secure the vehicle on a lift or jack stands to access the underside safely.
- Loosen and remove the factory muffler assembly clamps and hangers. Retain OEM hardware for potential reinstallation.
- Slide the OEM mufflers off the mid-pipe connection points and remove from the vehicle.
- Slide the Akrapovic S-PO/TI/8-TP titanium mufflers onto the OEM mid-pipe connections.
- Secure the muffler assemblies using the provided Akrapovic clamps and position the rubber hangers on the mounting points.
- Install the included titanium tail pipe set with carbon endcaps onto the muffler outlets per the included Akrapovic instructions.
- Start the engine and inspect all connection points for exhaust leaks. Retighten any clamps as needed.
- Perform a final inspection after the first heat cycle to confirm all hardware remains secure.
