Resident Clubdub Debbie Downer. I'd love your ideas if you kept them to yourself. Subarus suck, get a new wife.
Your description of the CEL is not clear. The work done will generate two CELs usually. Both can be addressed mechanically or electronically. Search "CEL fix" for both up pipe and down pipe.

DO NOT use a Cat in the up pipe. simple and cheap resistor mod will take care of the up pipe CEL.
