Ahh the flapping sound, I hear it too at 2500rpm. I'm running kooks lt, ypipe, cutout, and dual/dual exhaust! When the car had cats it soundedgood with the cutout open. Now with them gone, it gets the exact sound you are talking about at 2500rpm.I'm going to build a a y with a better merge and seewhat happens.
