firewall insulation - Downpipe install

Guys,

So what did you guys do about your firewall insulation doing your downpipe installs. Mine got a little torn up in a couple of places. i used a razor and cut some of the material off that pulled away from the insulation.

Do i need to worry that this could touch the downpipe?

Thanks

I ripped mine out, after it came loose and layed on the downpipe and turbo for months, it wont hurt nothing, either way.

If it is torn it need to either be removed or replaced....it is no longer good once torn....ie it can catch on fire.

I removed mine when i did my turbo.

mine never caught fire john,it was laying right on the turbo, trust me I tried to make it burn and I run the dog shit out of it. but yeah it is better to do away with it after it rips, it will look like crap and hang everywhere in a few months.

Hmmm I was guessing it was fiberglass....maybe it isn't??

The black stuff on top is fire resistant.

Either way I wouldn't run the risk of a fire.

no, probly not a good idea, the black stuff on mine just kinda came off little by little, it might have burnt off, but the yellow stuff wouldnt burn, it turned a grayish color where it got so hot over time but wouldnt burn.

On mines its the outer layer (real thin grey or black layer) that has pealed away from the rest of the insulation. I cut away the portion at top that wouldve layed near turbo but there is still some down by the downpipe.
