least your blow off is very original....maybe u got a australian skyline so instead of the japanese gozilla u got a australian kangaroo skyline...LMAO..sorry u must admit its funny if ur blow off goes "BOING"....if i was you id just goe to the nearest performance place..but if the tell that its a major problem and u gotta replace the engine or wateva bullshit they spin to try and fool u just remember to take it to about 3 places at least to make sure everyone diagnoses it the same
hope that helps a bit
