Duffy - Did you make a final decision on your exhaust?
Flowmaster does make the Super 50 with Dual 2 1/4" Inlets and 3" Outlet. They also make a 70 series in the same configuration which is just about the same, just longer and quieter.
My favorite, and not loud at all with great flow, is the Gibson Superflow - 758219. This muffler is reversible and has dual 2 1/2" Inlets and one 3" outlet. This one also fits the best too.
I, like you, am going to a quieter muffler.
