My Insulator pads in my pre-cats are rotted they are in between the heat shield and the pipes.
I'm thinking about replacing them with a Ceramic fiber insulation, all the way around the exhaust pipes then putting on the heat shields.
Question if I do this will this cause my pipes to get too hot? will there be any adverse affects?
pros doing this less rattle from the heat shield from heat transfer, transmission will stay cooler, engine bay too.
cons? less heat dissipation in the exhaust
