What Cory said. The fork gets disengaged from the throw-out bearing and the motor/tranny can get separated.

The sensor in the WRX up-pipe is an EGT sensor. You don't want to use it unless the Leggy ECU has an input for it that it needs. Even then, you can ditch that EGT and replace it with some resistors to prevent a CEL (at least on a WRX) as the EGT is only used for emissions to know when the up-pipe cat is at temperature.

As long as the stock up-pipe is of similar size, and is in decent condition, I'd use it rather than a catted WRX pipe. Or you could go all banzai on the WRX UP and drill out the cat... just try to avoid getting cancer while doing so. Either way, the less restriction and the less chance of something blowing through the turbo, the better.

Sounds like the compression on the motor may be down. If you've got the time and money, it might be prudent to pull the motor apart, hone the cylinders, slap on some new rings, and do the head gaskets while you're at it. The 22T block is a terrific block, but even it wears out with mileage. Get the compression and leak-down checked to at least see where you're at.
Or alternatively, a proper pair of catch cans will help keep the intake clean even with the blow-by of loose rings... allowing you to run the motor cleanly without spending the cash on a rebuild.
