The BCS Powervalve road legal 100 cell cat is the ideal hardware upgrade when considering a power increase on the 3.0 B58 engine. In addition, you will notice an audible uplift in the sound producing a nice sporty tone in the vehicle under acceleration.
The BCS Powervalve downpipe and 100-cell cat will connect to the OEM cat-back system with a minimum of fuss.
If you decide to upgrade to the full turbo-back system at a later stage then again, this is a straightforward procedure to complete the installation.
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 cell cat is a public road or track.
As with virtually all of the B58 engined vehicles, there is very little performance gain to be had from the cat-back system on its own, due to the incredibly restrictive 600 cell cat. However, by opting for our unique high flow cat which has a pipe configuration of 100mm into 90mm, 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 475 bhp achievable (along with suitable hardware...).
The fitting time for this product is 1 hour once the gearbox is cooled sufficiently for access to the stock cat mounting bracket to be gained.
