I realize the last post on this thread was like a year ago, but I was wondering if there was follow-up info on how the aluminum sheets held up covering the exhaust pipe. I'm considering doing a belly pan on my Del Slow using aluminum flashing. And I'm a bit concerned about covering over the pipes and how that might effect the car And pipes in the long run.
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.

Thanks,
Punch
