I'm aware of two projects that might fit your needs: https://github.com/tylertreat/Comcast calls out iptables or ipfw or otherwise depending on the underlying OS "to simulate common network problems like latency, bandwidth restrictions, and dropped/reordered/corrupted packets."
https://github.com/shopify/toxiproxy is "A TCP proxy to simulate network and system conditions for chaos and resiliency testing". Toxiproxy is probably closer to what you're looking for, but I haven't used it personally. It seems to be written in Go so they may expose something akin to net.Pipe.
