Not sure if the cat who bought out Schumacher is doing those again yet or ever.
If he does, I wish he'd do 1 7/8" primaries and a 3" outlet. It would be great to get that potential with stock type ground clearances. My 1/4" x 3" Hookers are pretty good for ground and plug clearance but I still drag on some speed bumps.
I suspect that the Try-Y config has a little more potential than TTI 4 into 1 shorties - maybe it's a wash.
These headers are going on a car intending to keep a low profile.
