Yup it's a 2.5. It's costing me 800.00 in labor. I'm a manager at Advance auto so I get great prices on parts. I can't seem to find any performance advise on the 2.5's. i don't want a race car but a little extra would be nice. i'm geussing exaust upgade but i'm going to have to do some custom work. I can't find any kits for a Legacy.
