The Scorpion is made to EU noise levels so is quieter and is not a complete system - only running from the CAT back. For the same money (or less
)the 'goose is a FULL system from turbo to tip with no restrictive backbox or silencers.
So yes, it's louder, but'll make y'turbo spin up quicker and it'll sound loads better.
Or get the 3" from Performance FX for max.gains :twisted:
