I think people have different opinions of drone/hum/volume is. I don't mind the volume of the G8 while cruising, but it does still have an annoying tone which I consider to be drone. Sounds nice at idle and accelerating.
My Cutlass has a build small block, headers and Hooker AeroChamber mufflers. It's loud at idle & WOT, and rather mellow rolling down the highway at 2,500RPM. While it's louder than the G8 on the highway, the tone of the sound is not at all objectionable.
Like you said, it's very subjective.
I just want to quiet down the idle a hair and get rid of the little bit of highway drone it has.
UPDATE: Swapped the Super Turbo axle back for stock GT axle back. Now it's so quiet I hear the intake more than the exhaust. Nice and quiet rolling down the highway though.
May just pull the factory mid muffler and install a small Magnaflow dual/dual muffler and just an X-pipe and call it done.
