Audi B7 S4 is one of the most popular performance sedans out there. It is known for its powerful engine and sleek design, but like any other car, it requires maintenance and upgrades. One of the upgrades that many Audi enthusiasts opt for is the downpipe removal. The downpipe is an essential part of the exhaust system that connects the turbocharger to the rest of the exhaust system. Removing it can improve the car's performance and sound. In this article, we will discuss everything you need to know about Audi B7 S4 downpipe removal.

Removing the downpipe can increase the exhaust flow and reduce backpressure, which can result in more power and torque. Additionally, removing the downpipe can improve the car's sound, giving it a more aggressive tone.
