Nevermind. I know not of which I speak.
It's the 80 series what I was thinking of, but the inlets are on either end.
Flowmasters are fairly free flowing though. If you want to get two 2.5" bullet type mufflers, that would be good, too.
Otherwise, you could reproduce the Borla/Bassani setup with a Flowmaster or Magnaflow in the middle and a resonator-type tip toward the rear.
It all depends on what you want to achieve and what you have to work with.
