Porche 971 Pnamera Racing Valved Exhaust system | GWAPOTech JAPAN
The muffler for the Porsche Panamera 971 is distinguished between:
3.0T model
Other grades
However, they share common components:
Downpipe
Center muffler
Rear exhaust
In this article, we first introduce the downpipe.
The OEM downpipe is typically composed of three sections, noteworthy for the large catalysts installed due to stringent emission regulations in recent years in the Eurozone, resulting in reduced sound volume.
Similar to other companies, we offer options such as a straight pipe configuration without catalysts or a 200-cell sports catalyst (*additional cost option). This is highly effective not only for sound volume but also for weight reduction and horsepower tuning.
Next, we introduce the cat-back system, an essential part of sound tuning following the downpipe. Here, we introduce both the rear exhaust and the center muffler simultaneously.
While we introduce center mufflers for both grades, the 3.0L center pipe utilizes an X-pipe design where exhaust from the left and right banks converges, designed to prevent sound distortion and achieve a refined sound quality.
This X-pipe design is compatible with center mufflers of any grade. Conversely, models without the X-pipe tend to prioritize powerful sound, allowing for customer preference.
In the rear exhaust, we employ a variable valve system that allows for switching sound volume according to the application.
To ensure a distinct ON-OFF effect with the valves, we use larger diameter pipes. In Silent Mode, the exhaust is designed to emit a volume similar to the factory setting, ensuring confident driving in nighttime and residential areas, adhering to gentlemanly specifications.
When the valves are open, the pipes operate independently of the tips, adopting a straight layout without exhaust interference, delivering a racing sound specific to NA engines. This enhances the everyday driving experience with this sound tuning item.
We also offer a wide range of options for rear exhaust tips, allowing you to choose the best design that matches your vehicle's image.
We provide competitive wholesale prices as well, so please feel free to contact us for inquiries!
