It's not clear that pipelining has anything to do with it. You have over 4 ns of data delay on this failing path. What would be really useful to see is the data arrival path section of that report to see where that extensive data delay is coming from. Also, make sure that your design is fully constrained for timing. Seeing your .sdc file would be useful as well.
