The exhaust system for the Audi S4/S5 (B8/B8.5) consists of:

  1. Downpipe

  2. Center Pipe

  3. Rear Exhaust

Let’s start with the front downpipe.

The stock center pipe is equipped with a very large silencer, which limits the 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.


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.
