The decat in the first link wont fit.

The DIT's cat is part of the downpipe from the turbo to centre section.

Someone else may be able to help you with the second link as i'm not sure if there's size differences between the 2.2 petrol and diesel

As far as I know the DTi engines only had the one cat underneath. I had mine chopped out and replaced with a piece of pipe by the local exhaust place.

It's not exactly on the downpipe as on CDTis, I mean it's not placed just after the exhaust, though it's one the same pipe (that's much longer on this engine).

It's actually after the flex braided connection, just before the central silencer, and exhaust specialists can unwield them and replace them with a tube - or hide it inside the emptied catalyser for MOT passing, wielding it back over the added tubing.

I just emptied mine using a rebar and fitted the downpipe back straight away.

It really helps the engine climbing up revs fast, and doesn't change anything for MOT, as they only check for smoke on diesels.

does anybody know what size pipe i would need to remove cat and middle box, also if it will just be straight section of pipe, if so i can just do it myself.

Just knock the guts out of your cat with a bar and then replace it. An incomplete exhaust system could be picked up on the mot and failed.

[garyvectrac]

no i would really like to keep the cat and just have a straight through pipe for both cat and middle section. does any body know pipe diameters at all.
