That still sounds pretty good xr6tman! I think very suitable considering your car looks nice and understated In regards to what PTR was saying, a lot of factors can affect the noise level/sound/each flutter length between different cars, as you mentioned you thought B series sounded louder than FG's. My BFII F6 had an under battery intake and ran similar boost to my FG, but they sounded quite different. (For those wondering both same turbo, GT3582R), but the FG had a standard side plazmaman intake. The F6 fluttered a lot faster, and was loud but less 'airy' or 'wooshy' for lack of better terms. The FG fluttered slower and though I wouldn't say louder sounded like more air pressure escaping... Bloody hell that was hard to explain.
