Not sure if this helps you guys but...

Many many many integra owners have junked their heat shields. Why? Because they have a bad tendency to rattle/resonate at 3500 rpm after xxx-number of miles. Is it harmful? Not that I can think of (considering aftermarket headerzzz don't have heatshields and make the engine bay pretty damn hot). The excess engine bay heat would be an issue if any of you are running shortram intakes, but that's being really nitpicky as well.
