As we enter the 2nd round (2016-2025 I think) of emission standards and fuel consumption minimums, it turns out that the car is in production. get really good emissions by raising operating temperatures. The problem is that the human body is uncomfortable outside and around a car that operates at or above 220°F. The production car is even worse. You save insulation around the cabin, so after a short period of rush hour, heat enters the cabin and no air conditioner can get rid of it. The cab simply stays warm until you're done driving for the day. I had to wrap the catalytic converters as they are so guilty in all this heat and although this wrap is expensive it works! It stinks as hell so plan your first travel cycle to get to the freeway, keep windows open if you're running recirculation, don't suck in fresh air. slightly looser in its weave. Soaking before application is a must to keep the fibers from floating. Finally, I only used this material for the exhaust manifold up to about 6-9 inches past the 1st set of catalog converters, at which point I switched to lava foil. Good luck with your project!
