Porsche 981 Boxster/Cayman Equal-Length Long-Tube Headers | GWAPOTech JAPAN
The Porsche 981 Boxster and Cayman consist of (1) a rear muffler and (2) headers.
Since they are composed of two sections, the role of each part significantly impacts the sound.
We have introduced the rear muffler in a separate article, so we will focus on the headers here.
This is the genuine header from the 981 series; however, due to stringent exhaust gas regulations in the Eurozone, a large catalytic converter is installed, which naturally reduces sound volume.
Additionally, the stock headers are unequal-length and have short tubes, which results in a muffled low-frequency sound.
Our company offers a straight-line specification option that removes the catalytic converter or a 200-cell sports catalytic converter* (paid option). This is very effective not only for sound volume but also for reducing weight and increasing horsepower tuning
As you can see, we have developed a specification that maximizes the length of each tube equally, like a wind instrument, in pursuit of the ultimate beautiful sound and high pitch.
Aftermarket headers for the 981 Cayman and Boxster are typically unequal-length and many have tubes that are as short as the stock ones. In contrast, our product dramatically improves sound in the high rev range and seeks to achieve a Ferrari-like sound.
We also have wholesale prices available, so please feel free to contact us!
