Frequently Asked Questions
What is the difference between S-PO/TI/8 and S-PO/TI/8-TP?The S-PO/TI/8 is the slip-on system without the tail pipe set included. The S-PO/TI/8-TP includes the Akrapovic Tail Pipe Set (TP-T/S/17/H) with double round titanium tails. Customers who already have Akrapovic tail pipes or prefer to use aftermarket tails should select the S-PO/TI/8.
Does the S-PO/TI/8 fit the 991.1 GT3 (2014-2016)?No. The S-PO/TI/8 is engineered specifically for the 2018-2019 Porsche 911 GT3 and GT3 Touring (991.2 generation). For the 991.1 GT3 (2014-2016), Akrapovic offers separate part numbers.
What tail pipe set is compatible with the S-PO/TI/8?The Akrapovic Tail Pipe Set TP-T/S/17/H (double round titanium tails) is specifically made for the GT3 991.2 and is the recommended companion for the S-PO/TI/8 when tail pipes are desired. It is sold separately.
Is the S-PO/TI/8 road legal?Yes. The S-PO/TI/8 in the slip-on muffler-only configuration retains ECE type-approval, making it road legal in ECE-compliant markets. In the United States, it does not carry CARB certification but is generally suitable for non-California street use.
What power and torque gains does the S-PO/TI/8 deliver?Akrapovic dynamometer testing shows gains of +4.6 kW at 4,200 rpm and +10.4 Nm of torque at 4,200 rpm versus the factory muffler on the Porsche 911 GT3 991.2.
Can I upgrade the S-PO/TI/8 with link pipes or evolution headers later?Yes. The S-PO/TI/8 is compatible with the Akrapovic Link Pipe Set (Titanium) and Evolution Header sets for the 991.2 GT3. However, adding these components will void the ECE type-approval of the slip-on system.
Does the S-PO/TI/8 also fit the 2019 Porsche 911 Speedster?Yes. The S-PO/TI/8 is confirmed to fit the 2019 Porsche 911 Speedster in addition to the 2018-2019 GT3 and GT3 Touring 991.2 variants.
Is the S-PO/TI/8 compatible with the Akrapovic carbon fiber rear diffuser?Yes. Akrapovic offers an optional high gloss or matte carbon fiber rear diffuser specifically for the 911 GT3 991.2 that pairs visually with the S-PO/TI/8 system for a complete exterior upgrade.
How much weight does the S-PO/TI/8 save?The S-PO/TI/8 saves 1.4 kg versus the factory muffler on the Porsche 911 GT3 991.2, contributing to a lower overall vehicle weight and improved rear weight distribution.
Does the Akrapovic S-PO/TI/8 come with a warranty?Akrapovic exhaust systems are backed by the manufacturer's limited warranty for defects in materials and workmanship when installed correctly and used as specified. Contact Black Ops Auto Works for full warranty terms and regional coverage details.
Installation Overview
