Thoughts of a well flowing exhaust for TT78 setup?

My thoughts are on a dual 3" setup, similar to the Kooks, back, over the axle, and stepped up to a 3.5" muffler on each side. I'm thinking Magnaflow. The car will be a street setup, so I want to keep the noise in check, but keep the flow up.

Im not sure on the outlet. Id like to run an x pipe, but there isn't room with the TQ arm I have, without going custom.
I guess I'm getting old. The car has been loud for 10 years. Im ready to move on to something else.
How restrictive will it be with 2 3.5 mufflers?
