The three vids aren't a great comparison, but they are indicative. The 'quietest' exhaust has the camera 24" from the taiilpipe! LOL!
I've found VERY little performance loss with recirculation. In doing so you aren't looking over your shoulder, or annoying everyone, each time you want to step beyond half throttle.
I even went with recirculating the BOV. Quiet and stealthy across the board. YMMV.
Let the acceleration and exhaust note announce your authority, not from a dump.
Good builds here. Carry on.
