The Audi S3 Sedan & Sportback are both a 306BHP masterpiece which rivals the likes of BMW M140 & the VW Golf R. With this in mind we have created a back cat system which adds another 18.3BHP to your S3. It doesn’t stop there, it also adds another 20.4NM of torque and reduces the overall weight by 4.1KG.

We also give you the option of a De-Catted with Cat simulator (this also allows you to choose between ceramic and non-ceramic coated). You’ll also find that there is a Sport Cat pip which has 200 psi Catalytic Converters (again with the option of ceramic coated or not).

If that wasn’t enough, we’ve also included an Armytrix key fob which lets you stand back and show off just how incredible the sound from your Quad exhaust really is. This allows you to show the difference between both sides of 3500 RPM and a Quiet or Loud mode. This is especially cool when you’re at a car meet or just looking to impress those around you.

Coloured tips are also an extra option you can choose if you’re looking to spruce up that rear end. So whether you are a sedan or Sportback driver, you can be sure that we have you covered with every possible combination that we have to offer.

We know that choosing the right exhaust can be exhausting but if you have any questions regarding the exhausts on display then feel free to contact and we will help you choose the right exhaust for your car.
