Full Titanium Race Sound for the 2018-2019 Porsche 911 GT3 991.2 and 2019 Speedster
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. The included titanium tail pipe set with carbon fiber endcaps delivers the signature Akrapovic high-rev howl that GT3 owners demand at the track. Installation is a direct slip-on connection requiring no cutting, welding or permanent modification to the vehicle.
Key Features
- Full Titanium Construction — S-PO/TI/8-TP muffler body and tail pipes are crafted from aerospace-grade titanium for maximum heat resistance and corrosion protection over a full racing season.
- Proven Power Gains — Dyno-verified +5 kW at 7,800 rpm and +12 Nm at 5,300 rpm on the naturally aspirated 4.0-liter flat-six of the Porsche 911 GT3 991.2.
- 9.9 kg Weight Reduction — System weight drops from 17.2 kg stock to 7.3 kg, improving rear weight distribution and lap times.
- Titanium Tail Pipe Set Included — Round titanium tips with carbon fiber endcaps complete the race aesthetic without requiring a separate tail pipe purchase.
- Authentic Race Sound — Produces the deep, resonant exhaust note that rises to a signature high-rev scream above 6,000 rpm, tuned specifically for the 991.2 GT3 flat-six.
- No-Cut Slip-On Fitment — Connects directly at the OEM mid-pipe junction with no cutting or welding required, preserving the ability to return to stock configuration.
- Track-Only Racing Use — The S-PO/TI/8-TP Race Line is designed for motorsport and closed-course competition use.

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.

- 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.
