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

The Akrapovič Slip-On Race Line (Titanium) is a precision-engineered exhaust system that brings out the true character and performance of the Porsche 718 Cayman GT4, Spyder, GTS 4.0 and Boxster GTS 4.0. Crafted entirely from lightweight, high-grade titanium, this system is designed to enhance every aspect of the driving experience—from sound and performance to weight savings and aesthetics. More than just an exhaust, it’s the finishing touch these models deserve and how they should have come from the factory. With motorsport-inspired engineering and a focus on lightweight performance, this system sets a new benchmark for track-focused upgrades.

Tail pipes are sold separately

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

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

The Akrapovič Slip-On Race Line (Titanium) produces a rich, harmonic tone that perfectly balances a deep, commanding growl at lower revs with a sharp, high-frequency note in the upper range.

Dyno testing reveals measurable gains, including +6.5 hp at 3,000 rpm and +11.7 ft-lb of torque at 2,900 rpm. The system also reduces weight by 6.5 kg—43.2% lighter than the stock exhaust—improving agility, cornering precision, and overall handling.

A modification of fitting brackets was done by Porsche on 718s produced approximately after February 2020.
