Porsche 9Y0 Cayenne Racing Valved Exhaust system | GWAPOTech JAPAN
The muffler set for the Porsche Panamera 9Y0 series is common across all grades and consists of:
Downpipe
Center pipe
Rear exhaust
First, we introduce each component starting from the downpipe.
In the OEM downpipe, there are two types of catalysts installed to thoroughly suppress gas emissions due to stringent emission regulations in recent years in the Eurozone, naturally reducing 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.
We have carefully calculated and fabricated the pipe diameter to ensure optimal exhaust efficiency and to avoid interference with the support bar, especially with the straight center pipe and the branch connecting to the rear muffler.
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 a larger diameter center section and design it to emit a volume similar to the factory setting in Silent Mode, ensuring comfortable driving in nighttime and residential areas, adhering to gentlemanly specifications.
Even when the valves are open, while the tube passes through the tip, we have meticulously calculated the tube punching, glass wool placement, and piping balance to achieve a racing sound, enhancing 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!
