I need help

I need help I am not sure what it going on I have had my 2001 F-350 for a year now I put on a 4" turbo back this weekend and am getting this wired noise when I put it in drive or reverse it is like a vibration slash rubbing or grinding noise that goes away as soon as I start to accelerate I have been looking all around under the hood and the truck I double checked the exhaust jacks up the driver side front end Fu#@ed with the 4x4 looked at my brakes hell I have even looked at the rock guard on the front of the truck everything is tight and seems to be in place I don't wana be one of those guys that blames the dealer but it happened the day after my oil change was done I know I have to be over looking something but I don't know I have been looking on the web for the last few days I am sure I sound like a total newbie but I wouldn't ask if I couldn't figure it out... thanks for any ideas

I need help

Yup .. Sounds like it might be hitting the side of the cross member under the cab ... I changed the Vband on mine and had the same thing. Sounds bad under idle but starts to go away when I took off

glad you found it My buddys' exhaust (downpipe) was hit'n the GROUND bolt on backside of motor. Laying right up on it. Removed it and relocated the ground strap to topside of motor. No more noise.
