I agree trying to sound deep never works. Go for the rally sound.
As for power gains - worry about that when you've got a set of forged pistons, rally cam flowed head, larger throttle body, proper tubular manifold, sports cat and remapped or Supersquirt ECU.
With the cost of that lot (plus insurance loading) you wont care about the exhaust back box. Anyway the Sportex manifold should work fine with the Ashley box. All the serious tuning happens up front anyway.
