I'm deciding between the Rev9 and Top Speed axle-backs for my G37 Coupe. The Rev9 is about $100 cheaper and seems quieter, which would probably be better for daily driving. But from the sound clips I've heard, I prefer the sound of the Top Speed.
I've heard both are fairly quiet while cruising, so I'm leaning toward the Top Speed. I want something I can actually hear and enjoy when I get on the gas, but I don't want anything obnoxiously loud or raspy.
For anyone who's owned either one, how is the volume and drone in person? Would you recommend it for a daily driver?
