Flexible Plumbing Option for 2" Indoor Drain Line?

Due to a basement project, I need to relocate the drain line for my kitchen sink from below the joists, to through the joists. I will need to drill through 3 joists in the process. Is there a flexible 2" drain option (like PEX) that will allow me to fish this new line through the joists in one piece, or am I stuck welding together several shorter pieces across the span? Thanks for the help!

How tall are your joists? Below is a chart showing how big and where it is acceptable to drill through a joist. As far as installing the pipe you'll probably have to use short sections of pipe and couplings.

I don't know of any generally code compliant flexible drain options. I think you're stuck with joining short lengths of PVC.
