IF you are running the factory down pipe and manifold (and maybe even a factory stock intake/IC piping, to fool them even more yet), HOW can the inspection Nazis tell if you are running an
external factory appearing HYBID, with bigger internal components/porting??
PLEASE do not tell me that they pull your snail off at every emissions inspection and compare it to a factory example they have laying around (or to an internet image or such)!!
