I just noticed that mine seam

 

Might save a pound or two, but your probably looking at a good bit more sound, and heat I believe (I forget where the heat issue comes in...).

If you just want to replace it, there are some alternatives such as a spray on insulation that is applied thinly and ends up being light and easy to clean.

 

There are quite a few people who have removed it. Billman has ran without it for over 3 years. I have ran without it for a year.

If you have a stock exhaust manifold it is not louder at all. If you have an aftermarket header, it will be slightly louder.

A lot of racers have actually removed it, not because of the 2 ounce of weight savings, because it will catch on fire!

Go for it.

 

Do you have any pictures of what it looks like with out it? Any heat issues, or issues of it affecting the paint?

Thanks.

 

eventually the paint on the top of the hood will go to shi t. over time the heat will destroy the paint, fading it and peeling the clear coat. this happend to my accord

 

i thought it was a good thing to keep it on for heat soak

 

Heat soak, that's what I was trying to think of (sorry almost done my 8 hours of labor and can't think quite straight ). If you remove the underhood liner, the painted metal acts as a reflecter for your engines heat, sending it back down into the engine bay. For a high-reving hot engine like ours, this can be bad.

So instead just get a new hood with vents!

 

Don't have any pictures... can take some tomorrow though. The paint is not clear coated underneath, nor is it the same exact color. It does not look ugly, but it looks different.

Regarding paint fading from removal... I would say it would take around 10 years depending on your climate. That is how long it took my truck to do it. When the S is 10 years old, you will be worrying about other things! My Accord is 16 years old, 4 of which on a DC Sports header... paint hasn't faded one bit. I am sure this is one of those "Your results may vary" things.

 

And who knows about heat soak... I guess just don't race in traffic.

 

I believe it's just for sound insulation although I've also heard it's a fire suppression device (melts during an engine fire smothering the fire???). As far as engine heat, I think it acts like a blanket retaining engine bay heat. The exposed underside of a hood should be a heat sink drawing heat out of the engine bay IMO.
