Hi, I have a '96 Outback, 113,000 miles, and the 'check engine' light came on. Computer says faulty catalytic converter(s), to the tune of $600. Another mechanic suggested trying a product called "Emission Pass". Has anyone ever heard of this, will it do anything, or am I out $600? Must say I've sunk a head gasket into this car already and am not sure what to do. Other than various engine problems, (burns oil), the car is great. But it's no fun wondering if the engine is going to die. Aprreciate any thoughts! Thanks, Holly
