what I understand is , the twins have a wider power band
for example
the S480 will spool late on small cuped engine like the 4.8 or 5.3 but will pull hard in the upper RPMs
and the 67mm will spool faster but dies upove 5500RPM
but twins will spool fast like the 67mm and still pull up like the S480

Twins you are taking 1/2 the engine so your turbo is sized for 1/2 the cubes.
Go to big and they well be laggy. To small spool great but die up top.
One big down fall to twins is fitment. It a small tight area on drivers side. Lots of wires, brake lines, etc.

I have a set of these headers on a project that is in the works. Single t-70 on a 5.3 in a 3rd gen camaro. They do fit nice but I did have to open up the rear most bolt holes to get them to bolt up. I tried to load some pics but they failed.

I had a pair of there shortie headers on my 5.3 for years, but after the first year, the welds broke, and that was in living in las vegas, no humidity. I had a local exhaust shop re-weld them, and never had a problem again. I thought I would throw that out there, because i wasnt running a turbo, and the welds went on them.
