Second Gear does not Sound Happy

Yes, I think it's time to replace the 5-speed in the WRX. At 158k, it's a bit disappointing. I drive it pretty hard, but the power is stock. I never redline the thing. I feel like it should have been designed for this kind of driving. The center diff blew up last year. Did Subaru phone in the post-engine drivetrain here?

If anyone finds, like, a thousand dollars on the ground and is not sure what to do with it, send it my way.

At least first and third are in decent shape.
