GReddy has a new Competition Ti-C that is a TURBO back. Full 80mm all the way. I went with it , and love it.

As for why US made 3" exhaust don't taper is for that reason, they're smaller than 80mm which allows the bolts to fit at the cat. Since Japanese companies use the metric system, 80mm is the closest size that you will get, thus making it impossible for bolts to fit at the cat, hence the taper.
BTW....that taper is negligible unless you go oversized to a taper and back to an oversize
