Where are you in CA? Do you ever come out to the Cerritos Monthly Meet? I'd love to hear how your Berk sounds like in person, I have this exhaust but haven't installed it yet because I also picked up the Ark grip V2, still deciding which one I like better. I've heard Ark in person before and sounds veryy good, but never the Berk, and YouTube vids just doesn't do the exhaust any justice. I Hope ure in socal so we can run into each other sometime.
