why did you decide to go with no egr?
also your fuel rail looks like the high volume svt rail not the 3.0 one. Did you modify it? My 3.0 one is much thinner than yours...
The black piping is simply piping. The banding is simply the outside structure, which helps keep the pipe from expanding under pressure.
If you're talking about the exhaust section, it's copper based exhaust wrap. It's made to keep heat inside the pipes. This helps keep the exhaust gases moving at a good speed instead of cooling down. It also helps with the temperatures under the rear shell. The copper based wrap is supposed to be about 30% more effective at keeping heat in than the standard 2000 degree F high end heat wrap. I sprayed it with silver heat wrap paint (also 2000 degree), because the orange copper color is ugly.
Nobles tend to need some good heat management. I had LizardSkin (ceramic based insulation paint) sprayed on the firewall and in the center tunnel. This stuff gives you about a 25-30 degree differential between the sides.
