The unique BCS Powervalve 90mm Cat delete pipe is the ideal hardware upgrade when considering a power increase on the 3.0 N55 engine (Electronic Waste Gate variant). 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 cat delete 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 primary use for the BCS Powervalve Cat delete variant is the track, or closed/private road, as this product is illegal for road use. 

As with virtually all of the N55 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 cat delete which has a pipe configuration of 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...).

Is my car the Electronic Waste Gate variant or the Pneumatic Waste Gate variant?

If you look to the left side of the engine, next to the water header tank, you should see the following configuration as shown below.

If you can see the empty bracket with the bolt protruding as shown above, then you have the electronic wastegate variant.

If you can see the configuration as shown in the image below, then you have the pneumatic wastegate, in which case navigate back to our parts list to select the appropriate part.

The fitting time for this product is 1 hour once the cat is cooled sufficiently for access to be gained.
