The Powervalve REV II Turbo-back (with the FLOW90 90.00mm road legal 100/200 cell cat) SPORT exhaust is our mid-range option for the Seat Leon Cupra ST 280/290 2.0 TSi, providing 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 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 Cupra 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 is public road or track.

The 90.0mm collector and ceramic coated surface on our unique cat provide unrivalled gas flow whilst remaining completely MOT and road legal.

The primary use for the Powervalve 100/200 cell cat is a public road or track.

As with virtually all of the TSi engined vehicles, there is very little performance gain to be had from the cat-back system on its own, due to the incredibly restrictive downpipe and twin OEM cats. However, by opting for our unique downpipe and high flow cat the power potential will massively increase, firstly with an initial 22bhp kinetic, and then once mapped all the way up to stage 3 the TSi 2.0 MQB Engine can achieve in excess of 500 bhp with our full turbo-back system and 100 Cell road-legal cat.

Our trims are now available with the Zircotec Volcanic Black finish.

Please select this from the option list if you require this finish.

Coating Specification

 Formulated to withstand temperatures of over 1050°c and thermal shock from those temperatures directly into water with no adverse effects

The trim options for this product are:

Typhoon/ Typhoon Black 

Dyno figures below show that the power increases before mapping by a massive 39bhp with the addition of an intercooler all the way up to 405bhp and 415ilb/ft of torque with Unicorn software.
