Reduced under hood temps. I think I remeber something about cleaner exhaust but don't quote me on that...

Does anyone know how that stock heat shield is connected? Is it just as easy as unscrewing it or does it require for the header to be removed too.

it makes the exhaust flow better believe it or not, the better you can keep the heat in the manifolds the easier the exhast can move through them. and cooler underhood temps is also a plus for performance too. im gonna do mine soon once i get a chance, i already have a extra front manifold that i took all the heat shielding off of including the shielding over the crossover and cleaned it up and im cleanin up the welds on the inside of the flange, the rear manifold wont be much fun gettin on and off, not to mention cleanin up the surface on the head around the exhaust ports to get a leak free seal.... probably a weekend project

So it would be near impossible to wrap the pipes without removing them right?

not impossible, but the best way to do it would be taking the manifolds off and removing the stock heat shields and heat painting the manifolds then heat wrapin the manifolds, some even suggest heat paintin the heat wrap after your done too. the heat shields are held on by rivots and i used a grinder to get them off.

Wrap your intake pipe! That'll keep the rad hose heat away from it too.

Ya I guess thats all I can do but it should help pretty good and then I can get me a heat shielded box like all of youz and be happy

REFLECTIVE on intake, hoses, wires etc. and "header" wrap on exhaust... one keeps the heat in .. one keeps it out.

wraping the headers keeps the hot excited molecules moving super psyco like through and out your exhuast, improving your exhaust velocity (one of those things that confused with the wives tale of keeping backpressure) ...basically your helping the engine help itself on getting the exhaust out faster... almost sounds like I stayed awake and learned something in physics class...

Note... nearly all header warranties are voided by wrapping them.

due to the fact that they can trap moisture in there and rust them out. Just something to think about.
