I've purchased a used Mugen Header, but it did not come with a heat shield. Is it okay to run the header without the header heat shield? Will the stock heat shield fit?

 

Mugen is one of very few (2 maybe) aftermarket headers that you can bolt the stock heatshields back on. You can run without them but your engine bay will get terribly hot.
I don' believe any aftermarket header comes with heatshields.

 

Thanks xviper!

 

The Mugen header comes with a heatshield. I have never tried using a stock shield on it but I question it will fit properly.

 

Well, there you have it. First hand experience.
It looks like the person you bought from didn't give you the shields.


As an aside ............ It is my impression that Rick's fashioned his header after the Mugen and his will accept the stock shields.

 

How about adding some sort of ceramic wrappings to those headers and underneath the passengers. My car gets terribly hot inside once I push it really hard. Anyone else gets this?????

 

The catalytic convertor is under the passengers floor. It's going to get warm no matter what to do to insulate it.

 

will be perfectly fine to run without heat shield

 

Although many have done it more heat radiates from the header without the shield. I would guess it will reduce battery life if nothing else.

 

Has anyone tried the ceramic wrap stuff. does it insulate well? does it fall off with rain/humidity???
I live in Houston and my car gets waaayyy to damn hot even at nights with the AC on!!. Maybe I'm driving too aggressively???
