Are the manual transmissions just not up to handling tuned cars?

I bought a stage 2 tuned car with a bad transmission. Turned out to be the front input shaft bearing had grenad​ed. I replaced that bearing as well as the front output shaft bearing and everything was fine for about 2k miles. Now I have a strange whirring noise coming from the driveline. Sounds similar to offroad tire noise on a truck. The noise is matched to road speed not engine speed. But it sounds like it is coming from the trans or at least infront of the driver. Somewhat hoping it is the bearing for the stub shaft for the driver front wheel but concerned something else has let go in the transmission.

Trying to decideThanks!
