Will these shocks work on a RD350 with stock pipes?

[Twidget]

I am looking for decent shocks that will work on an rd350 with stock pipes.  So far this is the best I could come up with, but I'm afraid they might be a little long for stock pipes:

Is 320mm/12.5" about the length limit for bikes with stock pipes?

Any other suggestions for good options out there that perform better than stock, but aren't $300ea custom shocks?

Or these?

It seems like what I might need are the red wing KM-S320's, but of course those are nowhere to be found.

yes, but will foul chainguard if you are running one. bit taller than stock but ive run them before.

Any significant difference between the Red Wing's and the Assault's?   

Equally crappy?

basically same thing. better than they should be for the money. i was always happy with them, ran them on the S2.
