The Vishnu UP-PIPE substitution does not have a catalytic converter. Removing your catalytic converter is illegal for street driving. Substituting your stock accessory pulley for an aftermarket underdriven accessory pulley without a harmonic damper will also void your engine and electronics warranty. Changing your ECU programming via a piggyback computer and adding a manual boost controller to increase your manifold boost pressure will also void the engine's warranty. You might not void the warranty if you change to a colder rating spark plug, but Subaru of America is going ballistic trying to void modified car warranties. This is illegal, but you'll have to fight for your right to a warranty. It will not be convenient.droidel said:I don't want to sound like the old lady in the group but I need to know, wIll the stage O void the factory warrenty?
no one mod will "void you entire warranty" there is no such thing. if your radio stops working for example, subaru will be hard pressed to blame it's malfunction on your uppipe or stage 0 componants.droidel said:I don't want to sound like the old lady in the group but I need to know, wIll the stage O void the factory warrenty?
