Cat C9 Exhaust heat shield

My exhaust pipe has a woven sleeve heat shield that is badly deteriorated . I would like to replace it with a better quality shield. Anyone know of a source for this or would it have to be custom made?

The section of pipe you discribe may be a vibration isolator, to stop the transfere of engine vibration from the engine to the exhaust.
Can you post a picture ?

I'd suggest you might call/ask your local muffler shop.

tbfirm, thanks for posting the picture, the accordianed area is your vibration flex joint and the wrap should be available from a auto / truck supply or muffler specialty shop. I would look into the posibility of water/ gravel spray from the wheels contributing to the failure of the original wrap. You may have to add a tin shield to stop that from happening again.

I am able to find the woven sleeve (fiberglass & basalt) online at truckpipesusa.com. I was hoping to find a better solution such as you suggest with a metal covering or such. This section of pipe is directly downstream from the regeneration unit and is subject to very high temperatures during regeneration to clean out the Diesel Particulacte Filter.

I am wondering if these high temperatures are the causing the sleeve to deteriorate.

If you look at the picture you can see the close proximity of the left rear jack which has a small leak at the lower hydraulic fitting which I believe is being caused by the extreme heat with the failure of the heat sleeve.

on my C9 cat the exhaust pipe has a heat shield to keep the temp down next to the transmission. I purchased a high temp pipe tape wrap from advance auto , then spray with high temp silicone, was an easy fix
