Porsche 718 Cayman GT4 / GTS 4.0 / Boxster GTS 4.0 | 2020 | Akrapovic | Slip-On Race Line Exhaust System (Titanium)

The 4.0 flat-six in the 718 GT4, Spyder and GTS 4.0 deserves a better voice than the standard exhaust gives it. Akrapovič's Slip-On Race Line is made entirely from titanium. It has a deep growl low down and a sharp, high-pitched note near the redline, and it takes a useful amount of weight off the back of the car.

Numbers

• 6.5kg lighter than the standard exhaust (43% lighter)
• +6.5hp at 3,000rpm and +11.7lb ft at 2,900rpm on Akrapovič's dyno
• All-titanium construction
• Akrapovič part number: S-PO/TI/18

Fitment

Fits the Porsche 718 Cayman GT4 and Spyder, and the 718 Cayman GTS 4.0 and Boxster GTS 4.0, from 2020, with or without OPF/GPF. Porsche changed the exhaust fitting brackets on 718s built after around February 2020. Give us your build date and we'll confirm the right parts.

Tail pipes: choose your finish

Akrapovič supplies the tail pipes separately from the system, so you'll need to add a set to complete the exhaust. Pick the titanium tail pipe set or the black titanium tail pipe set from the optional products below on this page and they'll be added to your order.

Complete the car

For the chassis, see the Ohlins Road & Track coilovers for the 718 GT4.

Fitting at String Theory Garage

We can fit this in our own workshop and check everything over before the car goes back to you. Get in touch when you order and we'll book a slot. See our workshop services for what else we do.

Questions we get asked

Do I need to buy the tail pipes?
Yes. The slip-on doesn't include tail pipes, so choose a titanium or black titanium set from the optional products below on this page.

Why are the tail pipes sold separately?
That's how Akrapovič supplies this system, so you can choose the finish you want.
