This is Subaru's definition for this code... DTC P2096 POST CATALYST FUEL TRIM SYSTEM TOO LEAN BANK 1; check this diagram about muffler assembly...

Fuel trim too lean. Usually means vacuum leak. Look for crushed,broken or melted off vacuum hoses near intake manifold. Or an obvious hissing noise at a normal idle. If so replace or repair clear codes your done. If not obvious take carb cleaner spray with nozzle attached car running & go over all vacuum hoses,intake manifold,egr valve see if idle raises if so you found leak. Repair. Could also be bad oxygen sensor switching bad o2 sensor but rarely.
