I had my entire exhaust ceramic coated which not only helps keep underhood temps down but it also helped with keeping the floorboards a little cooler. Also, my 16 year old Jeep easily passes Cali emissions and that's with a fat cam. Keeping the cats hot is key to low NOX and the ceramic coating helps by keeping the heat inside the exhaust. Does everyone need it, probably not but if one can afford it, then it does have its benefits.
