Proposed exhaust setup...
The hooker has one inlet, two outlets (to accept the conventional Y-pipe to I-pipe connection).
Therefore just have the X-pipe flow into two smallish mufflers or bullits, and have a couple turn-down tips before the axle if cost its a factor.

The headers, cam, and X-pipe mentioned... combined with the suggested bullets terminating under the car would equal enough drone to burst your head wide open in 3.5 seconds!

FWIW: IMO Hooker LTs & ORP with Hooker C/B would be awesome and cost effective. Maybe Zed the cut-out.
