Akrapovic Slip-On Titanium Race Exhaust - Porsche Boxster/Cayman GTS 4.0 718

Akrapovic Performance Exhaust — S-PO/TI/18

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.

Sound

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. Engineered for an exceptional auditory experience, the system ensures no unwanted drone, creating a refined yet exhilarating sound both inside and outside the cabin. This is achieved through the precise design of three mufflers—two side and one central—crafted in Akrapovič’s in-house titanium foundry. These components are meticulously arranged to optimise gas flow within the system's limited space, delivering a sound that lingers long after the throttle is released, amplifying the driving experience.

Performance

The Akrapovič Slip-On Race Line (Titanium) optimises the performance of the Porsche 718’s naturally aspirated engine by reducing back pressure and improving exhaust flow. This freer-flowing titanium design sharpens throttle response and enhances acceleration for a more dynamic driving experience. 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. These benefits are achieved without the need for ECU remapping, ensuring a seamless installation and compatibility with the factory setup.

Design

This exhaust system exemplifies Akrapovič’s engineering excellence and visual appeal. Constructed entirely from high-grade titanium, the Slip-On Race Line features three precision-configured mufflers for optimal gas flow and sound performance. The tailpipes, available in natural titanium or black finishes, are sandblasted and coated for durability, with an engraved Akrapovič logo and dynamic relief design adding to their aesthetic appeal.

Optional carbon-fibre rear diffusers, available in matte or high-gloss finishes, further enhance the visual impact of the exhaust tailpipes, blending functionality with striking design.

Modern exhaust regulations often limit the sound and character of high-performance vehicles. Akrapovič’s Slip-On Race Line (Titanium) restores the visceral sound and dynamic presence of the Porsche 718 lineup, making it the ultimate upgrade for enthusiasts who demand race-inspired noise and performance.

Designed for closed-course competition circuits, these systems deliver race-inspired performance while maintaining compatibility for everyday driving.
