What is the funtion of that plate on the exhust sys?

[Peterofdevon]

On my 93 of yore, that plate (about 5 x12 inches) fell off at about 100,000 miles. Never thought much of it. Yesterday, one came off my 94 at 85 miles per hour on the PA Turnpike--- thank god it didn't fly off and kill the guy behind me. The scraping sound sure scared the s h i t out of me.

Is it a skid plate or a heatsink?

Heat Shield?

While not a PHD in auto thermodynamics or mechanics and having NOT spent 10,000 + hours working on Q's, I'm not qualified to even own a Q let alone turn wrench on one. But, I'd bet money that gizmo is there to prevent your CAT from setting the grass on fire should you park in a field some day. Don't laugh, this actually happened in Virginia hunt country a few years ago at a polo match. Several VERY expensive cars were totaled by the conflagration.

My cat shield landed in a dumpster long ago. I don't park on grass unless it's damp.

That make perfect sense. Q45tech? Wes?

if you're talking about the heat shield on the cat converter, its just for what he said... Just dont park on a huge pile of dry leaves or grass...

I rip those puppies off when they start rattling...
