Jive_E46 Active member Aug 21, 2019 #2 What's up. It's just the open airbox(like the BMS one ), ie. Its not the stock closed airbox for the intake. People say the GFB DV+ makes the flutter noise but that doesn't make any sound at all. Sent from my SM-G965F using Tapatalk

Schalk94 Well-known member Aug 21, 2019 #3 Different intake and/or downpipe usually makes the flutter more audible
