The 100mm into 90mm downpipe, coupled to the BCS Powervalve 100 cell 125mm oversized catalytic converter complete with secondary cat delete pipes for the Audi RS3 (8V) has a gas flow ratio greater than any other product on the market, and having a 40grm wash coat which is up to 8 times greater than cheaper cats offered can, therefore, handle up to 10 years of hard life (...this is where the true value of the cat lies - in the precious metal content). 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 BCS Powervalve downpipe and 100 cell cat comes 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.
The BCS Powervalve road-legal 100 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.

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...).
