Exhaust manifold - made in Spain by AS - homologated

I think either to keep and mod it to make those 2 critical angles half of what is now by adding one more pipe and weld it.. or to return and do a full custom… the thing is I wanted to have cat in to pass emissions and mot/tuv no issue…
 
I meant I want it to pass TUV, here it is quite strict these days... if I remove the first CAT they will give me hard times.
 
Where are you from @Alert_ ? I think that if you leave the main cat there should be no problem. I just replace my old manifold with one that don't have the precat, leaving the big one. All the people that I've asked told me that it's ok like this to pass TUV
