hello guys. I know this sort of thing has been hashed out many times but never read anything quite like this . my squeal is only present at my tail pipe at rear of truck its a 2007 f350 straight pipe . 6.0 engine. 300'000 miles . just bought this truck . believe turbo has been replaced but not sure as to when . this noise is very loud ear splitting at an idle . any ideas ? builds boost just fine. no noise at turbo area other than the normal slight whine.

 

Squeal or a whistle?

 

I think he's not used to the awesome sound of a straight piped 6.0...........But I've been wrong before.

 

I sure hope you are correct my friend . everything else seems to working properly. im used to my 7.3 powerstroke so this is all new to me

 

well this is so loud its hard to say if its more squeal or whistle . could be declared both

 

Video a 30 second clip and post it.
