Slant six dual exhaust vs. 2-1?

Hey guys. I saw a guy with a slant six dual exhaust and I loved the sound so much. I’m planning on doing the Dutra Dual headers, and I’m wondering if doing the Duals into a single pipe has enough benefits to make it worth losing the sound of the 6cyl dual exhaust. My dad says the scavenging benefits are worth it in his opinion but neither of us have the experience with this particular set up so I’m hoping someone here does. What do you think? True Dual exhaust or 2 into 1?
A 6-2-1 system with the right length sections & merge points, or the DC/MP 6-into-1 header will make more tq/hp hands down. If You're smitten with the back&forth pulsation of separated duals, (2) 2" or 2 1/4" are still way better than a single 1 7/8" one, enjoy whichever You chose.
