Porsche 718 Boxster Spyder/Cayman GT4 F1 sound Valved Exhaust system | GWAPOTech JAPAN
The muffler for the Porsche 981 Boxster/Cayman consists of three parts: ① exhaust manifold, ② downpipe, and ③ rear exhaust.
Currently, our company is still in the process of developing the rear exhaust. Therefore, in this article, we will introduce the exhaust manifold and downpipe.
Let's start by examining the original equipment exhaust manifold.
In the original equipment, the exhaust manifold features unequal-length short tubes with large catalytic converters mandated by recent stringent emission regulations in the Eurozone. As a result, the sound naturally becomes quite subdued.
At our company, we employ a design that maximizes the length of tubes to be equal, akin to wind instruments, in order to produce beautiful tones. This design not only enhances high-pitched sound but also effectively contributes to weight reduction tuning.
Next, we will introduce the downpipe, which is an essential component for sound tuning following the exhaust manifold.
In the original equipment setup, similar to the exhaust manifold, large catalytic converters are installed which act as factors suppressing exhaust output.
By replacing this part with a straight design, not only will horsepower increase, but the sound quality at high RPMs will also significantly improve.
When considering F1 sound tuning for the 718 Cayman GT4/Boxster Spyder series, tuning of both the exhaust manifold and downpipe becomes essential. We highly recommend considering our products for their affordability and reliability!
