Rennsport-1 - I posted in your for sale posting re: your headers - can you PM your email address if you still have them available? Thanks, and thanks for the clip!
Stuart, I should take a clip and see if it shows up. I'm uncertain if it will be audible without load in neutral but it's worth a shot.
At idle, it sounds no different than stock from what I've noticed. PS - I need to come see you soon...I managed to run over what I can only refer to as Gandalfs staff the other night after that great storm we had here in DFW last week. Said staff managed to ding in the drivers side rocker panel a bit (grrrr).
