I want to keep the stock exhaust manifold/header and replace the rest. Is there a flange adapter that bolts up to the stock header and donut gasket?

just putting this here for my own reference, but something like this in the right size, this is too big:

What's closest? 2 inch or 1.75"?

Something like this in 1.75" tube?
