Flowmasters or Magnaflows on a V6?

Question

my brother is thinking about buying him a V6 mustang. He sent me these two links and trying to figure out if the flowmaster or magnaflows sound best. Any help would be appreciated. I like flows better on V8s but just trying to help him out.

Thanks!! :)
