Ok i got ya, yeah the Evo does come with a stock bov, altough i have the forge one but its still a lot louder without the top on.

same as on Evom people say its not good to take the top off, but yet they will throw a open filter on and say it works better lol..

Team Evo Staz: You know why they call it Skunkworks? Everyone: Why? Staz: Because everything that comes out of it stinks!!! Steeda-I hate you stazi
