Question Are All Catless Downpipes the same?

I've been looking at downpipes for N54 and most of them appear to look very similar (shape, size etc.). I guess the material and welding could be different...

So, are they all the same? If not, what is the difference and what to look for in downpipes?

Please help me understand it Thanks.
