i have a 2000 suburban 2500, 6.0 liter and i want a new muffler. I have read good things about corsa sport, but they dont make an option for the 6.0 L from what Ive researched. (they dont make a dual in, single out)

my stock muffler is dual pipes until the muffler where its dual in, single out.

what are your opinions? should i run true duals with a couple 50 series single in single out, should i run a 50 series for a 6.0l escalade with dual in single out, or should i get a 50 series dual in dual out and do some custom piping?

any ideas are greatly appreciated!
thanks
