I'm new to this so bear with me.
I have a 2002 F-250 4X4 Super Duty-Crew Cab with a V-10.
So far, I love it except for a "flutter" or something of that nature, in the exhaust.

 

Nice to have you here!

You can use the tech forums to find a solution to your noise, just click on the Forums tab at the upper left and scroll down over the list. The Super Duty board is always a good one and there is another board for your V10. You also have access to your state chapter: https://www.ford-trucks.com/forums/forum182/
