Sock filters over them defeats the purpose of a velocity stack.
Having the sock filters on the trumpets makes little to no difference on the performance compared to running them open.

During tuning we did back to back runs with/without sock filters and the difference negligable.

If you ran a box w/ good ducting and a super high flow filter I'd see them running more efficiently though.
