Dansk exhausts have always been like this, it's a design feature they built
into their jigs.  The set I put on my 2.1 12 years ago was a 1.9 exhaust had
that flange problem too.  I ground off some of one side and used two gaskets
and exhaust sealant which seemed to work well.

I was stupid not to.

Engine was out of van when I installed them (all except the collector). I
*thought* the mis-alingment was not that bad. With engine in, and needing
the van as a daily driver, I was reluctant to pull them off. So truthfully I
am annoyed by my own actions and by Dansk equally :)

cheers

flanges are not on the same plane, rather they are angled back, like a
dihedral. I tried stacking gaskets but no luck, still leaked. I would have
to grind off a fair bit of the pipe flanges to make them coplanar. I'm
toying with the idea of oxy-acetylene persuasion but probably will try
machining an angled "gasket" from mild steel. Meanwhile I used the tube of
goop David mentioned (Kleen-flo brand) and a little bit of rolled up ss mesh
to fill the gap. Then a bent strip of ss plate to hole the mesh in place and
the strip held in place by 2 right angled brackets attached to the flange
bolts.
