Focus RS Mk1

What more can be said on top of what you will almost certainly have read on the internet about the 76mm Ford Focus RS Mk1 BCS Exhaust system by Powervalve?

Its total uniqueness will provide you with everything you need to take the Focus RS Mk1 to its maximum power potential - the design features built-in pops and burbles and a drone-free experience...

With a choice of two sound profiles Sport and WRC we are certain that you will be able to identify the right choice for your individual requirements.

Which system should I choose?

In addition, the Powervalve 100 cell 125mm oversized  catalytic converters have 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).

Due to the huge increase in gas flow we recommend that the car is remapped to stage II in order to maximize the power potential of your car.

Fitting the system and cat without a suitable stage II remap may cause the CEL to illuminate.

Whilst we do offer a cat delete pipe you should note before purchasing that it is illegal to run your vehicle on a public road without a road legal catalyst installed. With this in mind, you should only consider a cat delete for closed road and/or track use.
