Exhausts manifold / headers heat shield

To anyone how has aftermarket exhaust manifold,

Did you guys heat shielded any of the coolant line near the manifold? The one I got came with some heat shield wrap for some of the coolant line under the engine. I haven’t got around to install them yet. How bad is it to run without the coolant line protected?

Dont know what your talking about. My header didn't come with anything of the sort. I just installed it and went on my way to more lag but better top end power.

I'm talking about all the coolant hoses under the engine. I believe there are 3 that are connected to the water pump, and 2 for the oil cooler. The header I got came with insulating material for wrapping those coolant hoses.

So how bad is it to not install them?

Well like I said I have my header installed and I DO NOT have anything wrapped other then the header themselves. However I wrapped the header for the sole purpose of reducing lag.

header heat

I have had the cusco headers for almost two years...they come with heat shields that are mounted on the headers via nuts. Well about a month after the install the studs holding the heat shields cracked and so i removed the heatshields...been well over a year. To date I have not had any issues with hoses melting or the heat warping anything..
