AUDI S4/S5 (B9)Racing Valved Exhaust system | GWAPOTech JAPAN
The exhaust system for the Audi S4/S5 (B9) consists of:
Downpipe
Center Pipe
Rear Exhaust
Let’s start with the front downpipe.
The stock downpipe is equipped with a very large catalytic converter due to recent strict emissions regulations in the Eurozone, which limits exhaust efficiency.
To optimize exhaust efficiency, we offer a straight pipe option as well as a paid option for a 200-cell sports catalytic converter.
Next, let’s look at the center pipe.
The stock center pipe features a large silencer, which restricts sound volume and results in a muffled, bass-heavy sound.
Our center pipe is designed to be a full replacement from the front pipe, significantly reducing weight compared to the stock one. It also features a resonator designed to minimize the impact on sound volume, delivering a cleaner sound. Additionally, the center pipe incorporates a Y-pipe design at the rear to enhance torque and create a powerful sound.
Finally, let’s discuss the rear exhaust.
The stock rear exhaust is equipped with a very large silencer, reducing exhaust efficiency and resulting in a muffled, bass-heavy sound.
Our rear exhaust is not only lighter than the stock one but also features a variable valve system that allows you to adjust the sound volume according to your needs.
The larger silencer is designed to match the sound level of the stock silent mode in silent mode, making it suitable for night driving and residential areas.
When the valve is open, the exhaust maximizes the engine's potential and delivers a racing sound, making it a great sound tuning item for enhancing your driving experience.
We offer a variety of exhaust tips options, so you can choose the one that best matches your vehicle’s image!
