I just took my header heat shield off today and I have to admit my engine bay looks better with the heat shield off...the only thing is that the stock header is rusty looking (so I was thinking about using Dupli's new MetalCast spray cans to spray it Anozied red), anyways how would removing this heat shield effect my car when i'm driving it...i mean it must be there for a reason, right?

It's so if you park under something flamable, it doesn't catch fire..ex. leaves. It also keeps things a little cooler, but I'm not sure..Mine is off, and I have no problems.

It's to keep engine bay temps down, you can imagine how hot a cast iron header can get on a 90 degree day. I have heard some stories of them getting so hot that they start to make the paint on the hood peel but I dont know how legit that is.

My paint did not peel, it just started to become very susceptible to chipping, as the hood gets much hotter than with the heatshield on. Since i put it back on, i haven't seen any new chips. Unfortunately it's too late...

Sorry to bring this topic up from the dead but it seems to be the most relevant one to post on.

I am getting a new exhaust made and ALL of my heat sheilds throughout the bottom of my car have been rusting off. Is It ok to take these of or are there any good replacements. This is one thing I don't want to go to the Acura stealership for.

With the exception of the Ex. Manifold and the Cat., you may want to go ahead and remove them. If they haven't started to rattle yet, chances are they will at some point. You shouldn't experience any negative effects from removing them.

I don't have a heatsheild on and the hood gets very hot, but no peeled paint yet. one thing I would suggest is putting some extra (fire-proof) insulation wrap on the Air Conditioning lines that run up and in front of the radiator. The unsheilded Manifold radiates enough heat to warm up your A/C system under the hood and lower the effectiveness it provides to keep your sweaty ass cool on a blistering hot summer day.

i was planning on doing aftermarket headers, any problems there or no, if so would the exhaust tape aid in reducing the heat output, i plan on getting a cf hood and dont want anything bad to happen to that.

It may raise the intake air temp. a bit, but 10 hp is a stretch.

IF you remove the Heat Shield under the Car my Recommedation is to replace it with HEAT BARRIER TAPE.

It is made of Carbon Fiber and a Aluminum like material.... Spoon sells some to keep the Oil from Cooking in the Oil pan.

This stuff is great it Blocks Heat up to 1600 degrees C. Weighs next to nothing and is QUITE functional.

keeps the Heat out of the Cabin if you remove the Sheild from the CAT.

Put it on the Oil Pan to sheild the OIL from HEAT.

Line the factory Heat Shield with it and keep the TEMPS under the Hood even lower

I have every single heat shield off of my car except for the one on the manifold and I have had them off for about a year now.. My car is in the air all the time at the shop and I can see no negative signs by taking them off.. all I have noticed is that the area right under the ebrake gets a little warm after heavy driving..
