i used the heat wrap on my tubualr manifold! the manifold cracked a lot so i have left it off this time to see if that curse the problem!
i thnk the best thign for u to do would b get the manifold ceramicly coated! it aint cheap but fook me it works! can cut the temps by somethin like 40%
as for heat sheild he ain local to u but lee @ fusion did some custom 1s for me i just desribed what i want & he took iot from there!
