Frequently Asked Questions

Does the Akrapovic S-PO/TI/9H fit both the Panamera Turbo and the Panamera GTS?

Yes. S-PO/TI/9H is designed for six 971 Panamera variants: the 2017-2020 Turbo, 2018-2020 Turbo Sport Turismo, 2019-2020 GTS, 2019-2020 GTS Sport Turismo, 2018-2020 Turbo S E-Hybrid, and 2018-2020 Turbo S E-Hybrid Sport Turismo. All share the same 4.0L twin-turbo V8 architecture and exhaust mounting on the 971 platform.

Are exhaust tips included with S-PO/TI/9H?

No. S-PO/TI/9H does not include exhaust tips. Akrapovic offers a full range of titanium and carbon tailpipe tips for the Panamera 971 platform that are purchased separately. This allows buyers to select the tip style and diameter that best matches their preference.

How much weight does S-PO/TI/9H remove from the Porsche Panamera?

S-PO/TI/9H weighs 11.5 kg compared to the OEM cat-back system at 28.2 kg, a reduction of 16.7 kg or 59%. On a grand touring sedan like the 971 Panamera, removing this mass from the rear improves overall weight balance and steering feel.

What power gains does Akrapovic publish for S-PO/TI/9H?

Akrapovic dyno testing on the 4.0L twin-turbo V8 shows S-PO/TI/9H adds 12 kW (16 hp) at 6,400 rpm and 20 Nm of torque at 2,700 rpm over the factory exhaust system. Both figures are manufacturer-verified from controlled testing on the 971 platform.

Does S-PO/TI/9H fit the Panamera Turbo S E-Hybrid?

Yes. S-PO/TI/9H fits both the 2018-2020 Panamera Turbo S E-Hybrid and the 2018-2020 Panamera Turbo S E-Hybrid Sport Turismo. The hybrid powertrain shares the same 4.0L V8 exhaust architecture and rear-section mounting points on these variants.

Does S-PO/TI/9H retain the factory catalytic converters?

Yes. S-PO/TI/9H is a cat-back system that replaces components after the OEM catalytic converters. All factory emissions hardware is preserved, maintaining street legality where applicable. No ECU remap or oxygen sensor modifications are needed.

Is S-PO/TI/9H a special order item and how long does it take?

Yes. S-PO/TI/9H is a special order item. Typical lead time is 4 to 6 weeks from Akrapovic’s production in Slovenia. Contact us to check current stock availability prior to ordering.

What exhaust tips are recommended for S-PO/TI/9H on the Panamera?

Akrapovic offers several tip options for the 971 Panamera including carbon fiber, polished titanium, and brushed titanium configurations. The Panamera Turbo uses a quad-exit layout. We can recommend specific tip part numbers based on your preferred finish when you contact us.
