ROAR on deceleration
I have a 2000 V10 4x4 Superduty regular cab long wheelbase. Above 55 mph, when I let off the gas quickly, I hear a loud groan from underneath. I only lasts for a second, but it is enough annoy a person. The truck has about 1,200 miles on it now. What could this noise be?

ROAR on deceleration
My uncle was recieving a very load noise around that speed, but it was at a constant throttle. He went to the ford dealer and it turned out that in 2000 they changed mufflers. The dealer ordered a 1999 muffler and it fixed it.
