The Powervalve road-legal 100/200 cell cat is the ideal hardware upgrade when considering a power increase on the 2.5 TFSi engine. In addition, you will notice an audible uplift in the sound, producing a nice sporty tone in the vehicle under acceleration.
The Powervalve downpipe and 100/200 cell cat come with a connecting pipe (which deletes the secondary cats) to allow you to connect to the OEM cat-back system with the minimum of fuss.
If you decide to upgrade to the full turbo-back system at a later stage then the installation is made possible with a minimum of fuss.
The dimensions employed on our unique cat will allow a gas flow equivalent to a cat delete pipe 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 TFSi 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 which has a pipe configuration of 100mm into 90m, the power potential will massively increase, firstly with an initial 22bhp kinetic, and then once mapped all the way up to a stage 3 and beyond, with figures in excess of 600 bhp achievable (along with suitable hardware...).
