Akrapovič Porsche Cayman GT4 RS/Boxster Spyder RS (718) Slip-On Line Titanium Exhaust System
This product is crafted from high-grade titanium with a sandblasted finish. It features two valves with housings made in Akrapovič’s in-house foundry, which tailor the exhaust sound—delivering a smooth, rich tone at lower speeds that evolves into a truly sporty sound at higher revs. The tailpipes are larger than the standard stock versions, with a coated outer and a cast inner shell that reacts with heat to develop an attractive blue hue. Each tailpipe is adorned with a laser-engraved Akrapovič logo.
Performance gains are significant, with power and torque increases of 5.6 kW (7.6 hp) at 4,950 rpm and 19.3 Nm at 2,250 rpm, as tested on the Akrapovič dyno against a Porsche 718 Cayman GT4 RS with a standard stock exhaust. Additionally, the weight is reduced by 7.6 kg (44.4%) compared to the stock system.
This track-oriented exhaust system requires no remapping and is specifically developed for use on closed-course competition circuits only. For those seeking further enhancements, the Akrapovič Slip-On Race Line (Titanium) can be upgraded with the optional Link Pipe Set (Titanium) and Evolution Header Set (Titanium) to create a full Akrapovič titanium system. Additionally, an optional handmade Rear Carbon Fibre Diffuser in matte or high gloss is available to complete the ensemble.
Fitment Notice: This product is compatible with both OPF and NON-OPF vehicles.
Note: This product does not meet emission compliance requirements for street or highway use.

In the words of the Vehicle Standards Agency (VCA), type approval provides "confirmation that production and samples of a design will meet specified performance standards".
For emissions components this encompasses noise, emissions and balanced back pressure, which have a strong influence on maintaining engine performance (power), and fuel efficiency. Type approval ensures that an aftermarket component will reach, or exceed the performance standard of the corresponding OE part.
Type-approval then, is a certain guarantee that an end user will receive a product of OE equivalent performance attributes.
Products on the Progressive Parts website that meet this approval will be clearly marked or labelled EC or ECE approved.
