If the atmospheric Flat-6 of the 718 Cayman GT4 is already rather pleasant to hear singing, Akrapovic offers a brand new exhaust to improve it.
Thanks to a 4.0-liter naturally aspirated flat-6, the production Porsche 718 Cayman GT4 already has a nice soundtrack. But there is always room for improvement. Akrapovic has just unveiled a new exhaust system that makes the engine roar more aggressively, while also improving performance. Made of titanium, Akrapovic’s “Slip-On Race Line” system takes approximately two hours of labor to install. A video posted by Akrapovic allows us to experience what the new voice of a Cayman GT4 looks like with the Akrapovic exhaust installed. A word of advice: turn up the volume!
Compared to the factory exhaust, the titanium Akrapovic exhaust weighs 8 kg less. Not to mention that the small reprogramming of the mapping necessary to change the exhaust line allows the Cayman GT4 to gain 15 horsepower and 43 Nm of torque.
So the Flat-6 now develops 430 horsepower and 642 Nm of torque. No performance specification has been released, but the change should improve acceleration slightly. For reference, the standard Porsche 718 Cayman GT4 sprints from 0 to 100 km / h in 4.4 seconds. If you want to drastically increase the performance of your GT4, you will have to wait for the RS versions which should soon point the tip of their spoiler.
More sport with the Cayman GT4 RS?
Last month, the future Porsche Cayman GT4 RS was surprised in full test alongside the new 911 GT3. It had a larger spoiler, multiple air intakes and aerodynamic elements in addition. In short, if the “classic” GT4 already prefers the track to the road, the RS version will be dedicated to it, while remaining approved for driving on open roads.
Power will be provided by the same 4.0-liter flat-six as the GT4, but a few improvements should allow it to develop 450 horsepower. Rumors have it that the power will be even closer to 500bhp, but that seems unlikely since Porsche won’t take the risk of a Cayman GT4 cannibalizing GT3 sales. While waiting for this nastier version, you have enough to scare 911 owners thanks to the Akrapovic line which may seem like a good alternative to make your Porsche Cayman even more aggressive.
