Installing this part allows you to enjoy more power while also making your vehicle sound better. One of the top brands is Milltek Sport with their exhaust system for the Audi B9 A4 / S4.
One reason why this brand is so popular among Audi drivers is that it has an appealing tone to it. It also looks good, which makes it even more attractive to buyers. This upgrade will give your car a sportier look and feel as well.
4. Suspension
Installing aftermarket suspension on your Audi B9 A4 / S4 will improve its performance while at the same time making it handle better.

Upgrading the suspension on your Audi B9 A4 / S4 will make it more responsive to steering input, providing a better cornering experience for you. This is a modification that all drivers should consider because it does provide many different benefits to you as a driver.
5. Tuning
An upgrade that is popular among Audi owners is through the use of ECU tuning. Installing an aftermarket ECU tuner for your Audi B9 A4 / S4 will improve its performance by maximizing its engine power, which allows you to enjoy more speed and better acceleration.
One example of a brand that specializes in modifying your car’s ECU is VR Tuning.
