I picked my '01 V10 up on 10/23. It had a build week of 10/02. I can say that I do hear what sounds like the flutter. It is not that bad. I can actually live with it. It sounds exactly like what everybody describes...a ticking or pinging type sound right around 2500 r's, and it does sound like an air blast hitting a thin walled steel tube. From the discussions about it, I thought it would be MUCH bigger in it's presence. It disappears with the radio at minimal levels

. I don't have any other V10 to compare mine to so maybe something has been done to lessen the affect in the newer 01's. Any part that replaces the existing Y-pipe will be a snap to install. Where's webegons report?
