I have a 2007 OEM impreza STi cat-back exhaust for sale in Redwood City that's had 6000 miles driven on it. I upgraded to an SPT exhaust and no longer need this one. It is currently sitting inside the box in which my SPT exhaust arrived -- I'd love it if someone wanted to buy it and swing by to pick it up one evening or during the weekend.

I'm asking $150, but if you like to haggle feel free.
