Oh ok do you think the ported manifold put you over the top?

I can tell you that it didnt hurt!

I think I'd be more concerned about the warranty. I remember having a problem with another vehicle, in which the header actually burned the harness for the crankshaft sensor. I don't know about headers.

well you can always wrap them to keep the heat down, and mine are being coated also.

I've heard talk about not wrapping these headers because of retained heat. I don't see why wrapping them would be an issue. I would think it would help keep engine heat/soak to a min. Could someone tell me why people are saying its bad.

Thermal wrap on a street car is usually a bad idea because the wrap traps water against the tubing and causes it to corrode very quickly. Race cars are rebuilt frequently enough for this to be a minor issue, but street cars are not, and headers have been known to fully corrode through the metal from water being trapped under the wrap.

PPE Engineering just got into the game, they need someone to volunteer their car.

you can coat them and wrap them....wouldnt it depend on what they are made from if it cause corrosion? i dont think wrapping them would create rust if they are coated and stainless.

I wouldn't risk the wrap. Coating for sure, but wrap is ridiculously heavy compared to coatings and it traps water.
