Exhaust wrap questions???
Posted 04 October 2003 - 11:01 PM
I have a 92 Loyale Wagon that has the catalatic converter right under the front axel and U-joint.
I have read many complaints about this design and that the heat damages the parts above it, so I frabricated a heat-shield, which helps a little.
I have read that using an "insulating exhaust wrap" can help reduce engine compartment tempatures, prevent heat damage to parts, and improve HP by reducing exhaust restriction.
So... what if I used insulating exhaust wrap on the cat instead of the metal heat shield? If I wrap just the cat, will that overheat it and damage it? Do I have to wrap all the pipes from the engine back to the muffler? Are there really any HP gains?

Be aware that reports of metal fatique from overheating have been coming back. This is usually from people who spend big bucks on headers only to have them crack and crystalize from overheating with the wrap in place. Its more of a race application thing and I've not heard many using it on a daily driver.
I think your heat sheild idea is the better option.
