Ceramic coating is probably the better choice for the street.
With the wrap on a regular steel header you will trap moisture and rust out
the header very quickly.
If you are using a stainless steel header and/or it will never see moisture
(rain or morning dew) then the wrap is a good choice.
I have a stainless steel Supersprint header that was covered with the heat
wrap for 3+ yrs. and it did nothing but discolor the metal a little (green).
I would have the ceramic coating done professionally, why? You probably paid
a lot for the header and another $100 or so insures that it will be done
right.
