Wrapping exhaust is good for race cars. Not so good for daily driven cars.

The good thing of the wrap is it will localize the heat along the header helping to funnel the heat down and out the exhaust system but can also trap moisture which will cause the header surface to oxidise, ruining the surface and forming cracks along the welds eventually.

Ceramic coating the better solution, which is oso the more expensive option...
