So my XJ was on the verge of catching fire due to heat from the cat/muffler area. Next month I need to smog it and the cat it beat up from rocks so I went ahead and ordered up a new cat and muffler (flowmaster). My question is, what are you guys doing for heat shields? My XJ has none. I'm thinking of warping the exhaust piping, but what about the muffler and cat? Can I just wrap those up too?

I wrapped my cat and muffler in fiberglass cloth then wrapped an airbake cookie sheet over them both and secured with long hose clamps. Then I built a 1/4" skidplate for the cat. This has worked fairly well for me.

Go to a Pick and Pull and get a set from a ZJ or I think a late model XJ. Not sure about the XJ. I do have a set from a ZJ on my XJ for many years.

I mounted them above the muffler and cat with self tapping screws into the body.

For those that used the cookie sheet, did you put anything between the body and the cookie sheet as a spacer for air to flow through?

I used a 1/8" spacer - just a thick washer basically.

You're still going to have to pull the exhaust parts away from the floor. The exhaust will still heat the floor without space between them. Then the heat shield will be efective in dissipating heat from heating the floor.
