S55 Downpipes

Hey all!

Looking to go catless on my m2c.

My current downpipes have some smaller pipes welded onto them. Anyone know what these pipes are for? See pictures, also adding a picture of downpipes from a m2 cs i found for sale, which seem to be similar to the ones I have.

I can't see any catless downpipes having these smaller pipes welded onto them.

Solved* it's differential pressure sensors for EU cars with OPF/GPF.
