NewGuy Posted July 11, 2008 Share Posted July 11, 2008 Some Guy was talking smack to me one day Tried to tell me he heat wrapped his whole exgaust in his van and it made it like twice as powerful. I Rofl and left. Id HPC Heat Wrap and shield if it was a problem. As my zaust is on the opposite side of the carbs i have no fuel Related issues wit heat etc. Quote Link to comment Share on other sites More sharing options...
RUNAMUCK Posted July 11, 2008 Share Posted July 11, 2008 I bought a roll of mr gasket header wrap. The speed shop that sold it to me said to wet it before fitting, so as to keep the fiberglass dust down. It's kinda nasty shit. I used hoseclips to hold mine on. I did a google search before I applied it, to see if there were any tricks. Almost EVERY page I looked at said it's crap. Supposedly it traps the heat, and accelerates the fatigue/degradation of the metal Even on cast manifolds. Plus it looks like shit. And oil and shit soak into it and smokes for ages. That HPC ceramic coating is the one to go for, but it costs lots. Quote Link to comment Share on other sites More sharing options...
Roman Posted July 14, 2008 Share Posted July 14, 2008 Everyone on the internet seems to say that it makes your manifold rust etc... But when I had heat wrap start to fall off mine and I pulled it off, it looked mint underneath, and rusty near the flange where there was never any wrap. Cant say I noticed a power difference though, but that's not why I'd fit it, personally. (or HPC) Quote Link to comment Share on other sites More sharing options...
