[Biturbos4] Alternate DVs for an S4

[Rich Shiba]

So i'm (finally) going to install a Y-pipe in my 2000 S.
I should change the diverter valves at the same time no?
I'm still running the stockers.

I haven't been paying attention too closely for the last
couple years, is the common (inexpensive) wisdom still to
use the TT valve?

The 710N or whatever it is?  Anyone have thoughts or even
better, a part#?

Thanks!
