I have a factory 93 EX CB7 with the F22A6. Yesterday I was cleaning the engiune area and decided to remove the heat shield. It looks alot better...except for the bright rust color . Does the engine bay require the heat shiled or is it just extra? Thanks!

Supposedly if it does it's purpose it'll catch most of the header heat to keep your engine bay temps down. If I were doing the job myself, I'd suggest taking off your header and cleaning it off...maybe with sandblaster...just enough to get rust off. Then, clean it off & apply a ceramic-coating paint that's heat resistant...maybe even specific for exhaust systems....I'm sure places like AutoZone would have that. It'd make it look even better since you're going for looks anyways....may as well keep it functional too. Ceramic-coating keeps the heat within the header.

I meant header wrap on a stock (non ceramic coated) header or SS aftermarket header....the ceramic coating was an alternative in itself w/no wrap.

The reason you have a heat shield is because the CB7 has no hood liner. So with the heat shield removed the heat under the hood gets so hot the paint on the hood will begine to turn white as it burns. Esspecially when it's raining. You can actually see the steam coming off the hood.
I'm running a Ceramic header. Even though it is ceramicly coated my under hood temps are still quite high. I plan to fashion a hood liner to preserve my hoods piant after my car gets painted.
Header wrap is the worst thing you can do to your header. The header gets so hot and the heat can not disapate so the header can actually reach it's melting point. Even then after metal is heated it becomes more maluable so it is easier to bend and tends to split.
