The '02 is a special beast.... and '03.

You actually CAN run a full turboback and uppipe without a tune, however, you will get better results and be slightly safer with the tune.

You CAN NOT do this with other WRXs.

I say go for it, but pick up something even as simple as an AP down the line. Or get protuned, etc. Your choice. But it doesn't have to be ASAP.
