The Powervalve REV III Turbo-back (with cat delete pipe) SPORT exhaust for the Audi S3 2.0 TSi, provides you with a perfectly balanced sports tone both externally and internally above the stock exhaust note, when the car is running off boost (Cruising and driving sedately). However, as you are no doubt already aware if you are looking to create the best possible audible thrill…

Powervalve offers a unique perspective on exhaust technology, providing the driver with the option of two distinct natures. When the car is pottering around or cruising the sound is at once uplifted and noticeable yet controlled and non-intrusive. However, once the car is driven aggressively and produces a key level of boost pressure everything changes and the sound becomes purposeful and redefined reflecting the true essence of the S3 2.0 TSi. All of which are under the complete control of your right foot, therefore, you determine the sound minute to minute depending on your particular driving requirements. By using this unique interaction, the driver ceases to become desensitized in the way you would with a non-variable sound, leaving you looking for more time behind the wheel…

The system has a greater audible volume than the cat back offering, however, with careful design and development we have created a system that ensures that any unwanted in-car frequencies are removed, leaving you with a perfect drone-free experience, together with our characterful pop and burble, free-revving sound.

The primary use for the Sport variant system with cat delete is the track or closed/private road, as this product is illegal for road use.
