    Not sure what the bore is, but any fabricator will make it to suit the existing bore. Decats work well on the CDTi too, I have mine booked in for removal for my Powerflow system.

    With a larger bore centre back, you still have the bottle neck of the manifold/down pipe sizes - its best to match the existing bore while removing centre box and using free flow silencers on the back box(es).

    Parsco on here has recently decat'd and removed centre box on his VXR system on his CDTi - he even up'd a video too.

    I have the centre box removed already - just need the decat now

    The fact its a 6 cylinder helps too!!!

    Mine is currently CAT back with no centre box leading to the two rear boxes. Better pick up and an awesome deep noise when booting it.

    As Dan has said, remove all boxes and CAT and just have the rear box(es) on the back. You'll get a nice turbo whistle and a deep bellow when you boot it Also the OEM recirculating dump valve is a bit louder too

    (check my video in my signature for more reassurance )

    You don't need a CAT for a diesel. The MOT only goes on a soot test and the CAT does NOT reduce the amount of soot that goes out the back of the car. The reason diesels are built with CAT's is to pass the initial EURO 4 emissions tests and then they never have any

    Do it you'll love it
