Titanium Performance for the Cayenne Turbo: Akrapovic S-PO/TI/17H Evolution Line Cat-Back
The Akrapovic S-PO/TI/17H Evolution Line Cat-Back exhaust in titanium delivers a commanding exhaust upgrade for the 2018 to 2020 Porsche Cayenne Turbo and Turbo Coupe, including the Turbo S E-Hybrid and Turbo S E-Hybrid Coupe variants. Engineered for the 536 platform's 4.0L twin-turbo V8, this system reduces weight substantially over the factory exhaust while producing the rich, layered titanium exhaust tone that defines the Akrapovic brand. Note: this system requires separately purchased Akrapovic exhaust tips for a complete installation.

Frequently Asked Questions
Which Porsche Cayenne models does the S-PO/TI/17H fit?The S-PO/TI/17H fits the 2018, 2019, and 2020 Porsche Cayenne Turbo, the 2020 Cayenne Turbo Coupe, the 2020 Cayenne Turbo S E-Hybrid, and the 2020 Cayenne Turbo S E-Hybrid Coupe, all in the 536 generation (3rd gen, E3) body style with the 4.0L twin-turbo V8 engine. It does not fit the Cayenne S, GTS, or base Cayenne models.
Why are exhaust tips sold separately for the S-PO/TI/17H?Akrapovic offers multiple tip options (titanium round, carbon fiber, and various finishes) for the Cayenne Turbo 536 platform. By selling the cat-back body and tips separately, they allow buyers to choose the exact tip style that matches their aesthetic preference. The system is designed to accept Akrapovic's tip system, and the correct tip SKU should be added at the time of purchase.
What is the sound character of the S-PO/TI/17H on the Cayenne Turbo?The Akrapovic S-PO/TI/17H transforms the Cayenne Turbo's exhaust note from the subdued, insulated factory tone into a deep, authoritative V8 exhaust soundtrack with a pronounced titanium resonance. The system maintains composure during normal driving while unleashing full sound under hard acceleration, particularly above 3,500 rpm where the 4.0L twin-turbo V8 begins to build serious boost.
Is the S-PO/TI/17H compatible with the Cayenne Turbo S E-Hybrid?Yes. The S-PO/TI/17H is confirmed to fit both the 2020 Porsche Cayenne Turbo S E-Hybrid and the Turbo S E-Hybrid Coupe. The hybrid powertrain does not affect the exhaust system fitment as the cat-back section interfaces with the same exhaust routing as the standard Turbo.
How much weight does the S-PO/TI/17H remove from the Cayenne?Akrapovic's Grade-1 titanium construction delivers significant weight savings over the heavy factory stainless steel exhaust system on the Cayenne Turbo. While Akrapovic does not publish the specific weight delta for this system, titanium cat-back systems on comparable platforms typically save 10 to 15 kg versus OEM.
Will the S-PO/TI/17H work with the Cayenne's active exhaust and Sport Chrono package?The S-PO/TI/17H is designed as a direct-fit system for the Cayenne Turbo 536 platform and is intended to be compatible with the Porsche active exhaust and Sport Chrono features. The factory valve actuation system and its associated Porsche Drive Modes integration remain functional.
Does the S-PO/TI/17H require any ECU tuning or software changes?No ECU tune or software modification is required to install the S-PO/TI/17H. It is a direct bolt-on replacement for the OEM cat-back exhaust. However, some owners choose to pair an upgraded exhaust with a performance tune to maximize gains, which can be done independently of the exhaust installation.
Is this system legal to use on public roads in all US states?The S-PO/TI/17H retains the factory catalytic converters and is not a decat system, making it street-legal in most US states. However, California and some other CARB states have stricter requirements, and this system carries a Non-CARB designation. Check your state's regulations before purchase if you are in a CARB-regulated state.
Can I install the S-PO/TI/17H at home without a lift?The Akrapovic S-PO/TI/17H is a bolt-on system, but the Cayenne's ground clearance and the weight of the titanium cat-back sections make professional installation on a proper lift strongly recommended. Attempting installation without safe vehicle support risks personal injury and may result in improper fitment if exhaust hangers are not correctly seated.
Installation Overview
- Allow the factory exhaust to cool completely before starting work.
- Raise and securely support the Cayenne on a lift or jack stands rated for the vehicle weight, with wheels chocked.
- Apply penetrating lubricant generously to all OEM cat-back fasteners, flanges, and rubber hangers and allow 15 minutes of soak time.
- Disconnect the OEM cat-back at the mid-pipe outlet flange and note the gasket condition.
- Release all rubber exhaust hangers and lower the factory cat-back assembly carefully, noting its routing around the rear suspension and heat shields.
- Clean both mating flange faces and install the supplied gasket.
- Position the Akrapovic S-PO/TI/17H system and connect to the mid-pipe flange, hand-tightening only at this stage.
- Route all rubber hangers onto their respective mounting pegs, verifying the system hangs without contact with any chassis or heat shield components.
- Install the separately purchased Akrapovic tip assemblies per their included instructions before final torque.
- Torque all flange fasteners to the specification in the Akrapovic installation sheet, working evenly from front to rear.
- Start the vehicle and check all joints for leaks. Re-torque after the first full heat cycle once the system has cooled.
