Just wondering is there anyone that has heat wraped there. Headers an. Is there any. Benefit to doing it???

Underhood temp decreases but the cracks tend to happen.

There would be a benefit of course as it would cause less heat to engine bay however it is a gamble. Heat wrap generally introduces the chance to rust and has a tendency to harden the metal due to the heat being contained and make it more prone to cracking.

There a waste to wrap unless your wrapping the turbo exhaust. All it does it decrease heat but no performance gains. Unless on a turbo car

It isn't good for cats either, is it?

I run open headers so IDGAF lol, j/k ... dunno most people when worried about heat run ceramics, don't know anyone these days that wrap.

Ya I wouldn't do that. Especially after looking at how hot they an get. I had my car idling in my garage and was playing with my new laser thermometer and just from idling (not even at normal operating temps yet) the cats got up to ~375 degrees. I've heard they can get up to around 800+ after hard driving.

Damn that's hot

Hood vents would be the best solution. The 13+ cars are good examples as it would allow the heat to simply flow out of the engine bay so your plastic parts and wiring are heatsoaking.

They aren't that functional. The one on my Evo sure as hell was though.

Trim away the hood carpet underneath them and they become a lot more functional. I can literally see the heat waves coming from the hood when I'm sitting at a light after driving for awhile.
