AFAIK, neither. Having had 3 different-than-stock exhausts on my van, due
to having
3 different engines in it, I'd take a stock1.9 or 2.1 to a fabricator and
have them build
one that would fit, but using the newer parts/technology, to include
ceramic coating.
And build it with mild steel, which most of those kinds of shops do anyway.

You will accomplish all three of your goals. Have the shop use black
coating,
it is about 70% better at trapping exhaust-gas heat inside the pipe than any
other of the commonly used colors. The effect of that is better performance
and
mileage.
