I have 2. My wife's 2010 Forester XT:
and my 2004 Forester XT 5spd.
Her car is as stock as stock can get. Mine used to be hers that we bought brand new when they first came out in the fall of '03. I replaced the turbo with a VF39, gutted the stock uppipe and picked up a STi muffler and WRX IC. With an OpenSource tune is made 241whp @ 15psi.
This was done while she was driving the car, so we left more power on the table to have a safe tune. It's at able 145,000 miles and still runs great. I picked up some stock struts to use as Koni cores with Swift springs. I might get some newer FXT wheels later.
