some use a cat, later cars (generally 2007 on) use a particle filter.

Diesel engine don't need a cat because they only do a smoke test for MOT

One thing I was wondering. How come they don't put centre boxes on diesels? Mine isn't loud, but it's not really that quiet either. Plus it doesn't sound that good really

TD engines dont have centre silencers due to them being very quiet engines, the turbo itself silences most of the noise.

Dave, does removing the cat (decat??) provide any sort of performance differences?

I thought that too, I had my fingers crossed with the Fiesta and I was massively, massively wrong

Diesel engines are inherently quieter too, which helps.
