The OBS stock housing is 1.15 and it is non-gated. The EBPV outlet is different as is the flange for the down pipe. The OBS collector is a T4 flange instead of a v-band. It wouldn't be worth the effort to make it work.

Collector... excuse my ignorance, but is that the exhaust flange? If that's the case, how hard would it be to use OBS uppies and a T4 turbo and just fab up a mounting bracket for my truck?

The OBS up pipes should work on your E99, but they are the donut gasket style and prone to leak just like the SD up pipes. Murff racing makes a nice T4 mount that is very affordable... unless you are just dying to do some fab I'd go that route.

I've seen a guy that used a stock OBS collector (aka exhaust flange) to build a T4 mount for a GT45 but it was in an OBS truck.
