If I had to guess, manual and stouter gears.
I doubt I'd feel little if any bottom end difference with the stick and 3.73s in my '15.

not cheap by any stretch but manifold experiments aside, wouldn't a 3.55 be a big help?

Nice work.
As mentioned above, folks need to keep in mind that different mods will work differently (or appear to) based on other factors. The truck manifold seems to work well with the 3.15 gear car the OP has, and understandably so. The same setup on a manual 3.73 car probably would be counter productive.
When I did my 18 GT manifold, I didn't really notice a whole lot of change. Little bit more up top and little less in the midrange. Once I added the long tubes, it worked together perfectly.

I installed the GT350 IM on my 2016 A6 this weekend. Best 0-60 has been a 4.34 on the street with narrow stock size tires. The car doesn’t feel like it lost anything down low, but doesn’t feel significantly faster either. Although the DA was about 1200 ft higher than the last time I used the dragy.

What rpm are you shifting at. From what I gather those manifolds like the 350, cobra jet, boss and even the 18 have to shift at very high rpms to see benefits

7700 rpm.
from about 5500 rpm it felt like it came to life. Not that it was slower below that, it just really woke up around then.
I need to datalog and send to my tuner. He wants to make sure everything looks good.
It doesn’t feel like I lost any tq though. It was making 483 rwtq with the stock intake running E85.

Cars on a NT555R2 it spins on 1-2 shift but you can drive through it
