Exhaust Insulator Pads in the Heat shields
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 http://www.amazon.com/Ceramic-Insula...ber+insulation Last edited by kjoyes; 08-13-2014 at 05:29 PM. |

Re: Exhaust Insulator Pads in the Heat shields
Designed to keep the exhaust gases hotter from the headers to where they enter the pre-cats.
I removed the heat shields entirely on my 96, have 2" aluminum tubing directly from the headers into the pre-cats. No performance problems or other issues. I am not sure how much measurable difference there would be between insulation and bare tubing for that short length and its effect on performance. I am sure there are various opinions out there. Since insulation works best when it is not as tightly compressed (think home insulation) maybe 1/2" insulation would work better. Insulate and allow some air circulation without being too compressed. http://www.amazon.com/Ceramic-Insula...ire+Wood+Stove .

No realistic effects either way
