The exhaust wrap I've got is auto specialist stuff from MSD so should be ok as I done think they'd sell a shit product.
My downpipe was wrapped before on my old spec and had no issues with it but dont know what type was used.
Main thing I was interested in was heat resistant tape for boost hoses, not downpipe.
I've took a chance and ordered some of this stuff

Will asllo get some of this to make up some heat sheilds
