hi guys any idea how much heat wrap is required to wrap a set of headers and up pipe? ie 1"x50' thanks

 

i think you can just get away with 2"x50'

Harvey is the man you need to ask about this. from what i have seen, he does a very good job with it

 

Thanks Ian.
2"x50 feet roll of DEI heat wrap will generally do a set of tubular headers and up-pipe. A further roll of the same is required for a 3" down pipe with a little left over.
Get in touch if you want some DEI heat wrap.
