Was there an increase in internal heat? Did or would the heat of the pipes be conducted across all the metal keeping things cooler? Should space be left around the cat. converter? Any feedback is appreciated.

I'm actually only using one sheet of aluminum to cover that ONE section of exhaust piping to connect the front and rear section of corplast, and it is holding up very well in terms of heat. Otherwise, I have about 3-4 inches of clearance between the coroplast and exhaust pipes and have not had any issues of heat melting the corplast either.
Aluminum is an excellent conductor of heat, but one of the concerns people have with underbelly trays if you were to have an exhaust leak, there is no where for the exhaust fumes to go but into the passenger cabin area. I didn't want to take that risk, therefore I left the bulk of the exhaust pipes uncovered and only lined front, sides, and rear of under the car with coroplast.
