How can I improve my Audi's horsepower?

My Audi seems to be lacking in power and acceleration. Is there any way to increase the horsepower without compromising the engine's reliability?

One way to improve your Audi's horsepower is by installing a performance exhaust system. This will not only give your car a more aggressive sound, but also increase horsepower and torque.

Another option is to install a performance air intake system. This will allow more air into the engine, resulting in an increase in horsepower and improved overall performance.

You could also consider upgrading the engine's software through a chip tuning. This will optimize the engine's performance and potentially increase horsepower.
