[Shop-talk] header wrap

[Neil Sherry]

Hi Tim,

I agree with Karl - definitely not the right thing to fix a hole - your 
tin can would be better employed straight on the hole, if you can't do a 
welded repair. And there will be vibration in the pipe - flexipipe is 
mainly to cope with rocking back and forth of the engine as power goes 
on and off.
