Motor sounds real crisp in both vids Scott,I love the sound in each but I can tell what you mean about them being more on the trembly side.Can't wait for some WOT vids next...
I've always been a Flowmaster guy and run the new Super 44's on both Z/28's and just love them when I open 'em up.I never drive with any passengers nor do I have any music in either car (except for the engine

) so I love the drone and I love the resonance...just love it.
Carry on man...your car is beautiful.
