Anyone regret NOT wrapping their headers before installing?

I wouldn't hesitate to recommend the titanium wrap for headers. Underhood temps, pipe resonance, and proximity to critical components (wires, brake lines, clutch lines, starter, etc) made it an easy choice for me.
$90 to wrap a pair of headers.

Non flammable, non-wicking, any moisture evaporates very quickly.

I've thought about thermal coating, but does it actually DECREASE temps, or just make it cool to the touch sooner once the car is off? I mean, how drastic are we talking here?

dr whigham, Try driving it with the AC on it should run cooler.
I'd have the cooling fans set to lower turn on temperatures, they're set fairly high from the factory.
C5 Cooling Fans Operation
The low speed cooling fan is commanded on when the coolant temperature reaches 108°C (226°F). It is turned off if the coolant temperature lowers to 104°C (219°F). The high speed cooling fan is commanded on when the coolant temperature reaches 113°C (235°F). It is turned off if the coolant temperature lowers to 108°C (226°F). When the A/C is on and the coolant temperature reaches 85°C (185°F), the low speed cooling fan will be turned on at vehicle speeds less than 56 kPh (35 mph).
