Stainless or alloy exhaust guard tray

Just be aware it is functionally structural in terms of chassis stiffness/bracing apparently
Do you mean the exhaust?I would naively assume that the exhaust needs to move about with the engine, hence couldn't be rigidly attached to the car's structure.
I'd be interested in some kind of protection against grounding. I've scraped it a couple of times recently, and it's definitely the exhaust that takes the brunt. Are the exhaust and its mountings reasonably tough, or is significant damage likely to occur due to grounding?

Not the exhaust, but there is a plate that's about 35cm X 58cm that covers the expansion box and is held in place by six bolts. It stiffens the chassis (apparently I would naively assume that the exhaust needs to move about with the engine, hence couldn't be rigidly attached to the car's structure.

) and supports the exhaust.Its unlikely (but possible) that your exhaust is what's grounding. The parts under mine that are nice and shiny are the ends of the bolts for the front anti roll bar.

Not the exhaust itself but the tray that bridges the chassis rails with the silencer box above. The exhaust is flexibly mounted, includinmg to this tray and can/does take a surprising amount of abuse reasonably happilyI would naively assume that the exhaust needs to move about with the engine, hence couldn't be rigidly attached to the car's structure.

Ah, yes - I know the bit you mean. It's got two fairly large circular holes cut into it, if I remember rightly. ) and supports the exhaust.I'm finding that the exhaust can strike just forward from that plate - evidenced by fresh shiny metal! It generally happens if I go too fast over an undulating road: as the back wheels reach the bottom of a dip and the suspension compresses, the exhaust further forwards grounds on the next "peak" of the undulation, particularly if the road also has a pronounced camber across its width. It could be worse; at least it's not the sump!

If you have adjustable suspension, make sure your ride height is set correctly.
The standard springs are surprisingly soft, (for their limited travel).
A change to +20% stronger springs makes a world of differance, no more bottoming out!
Call me thick, but I cant see how this stiffens or braces the chassis. There is however, a brace behind the gearbox bellhousing which I could believe does this job, but the exhaust plate is a wobbly tea tray type of affair that just supports the exhaust centre box...isnt it? The only thing it might do is to act in tension to stop the bottom main chassis sections from splaying apart, but is it really man enough for this?
Photo of brace bar fitted to chassis behind gearbox attached. You can see it has some thickness to the section unlike the exhaust tray.
There has however been some thought put into the exhaust tray mounting - by varying the number and placement of washers between it and the chassis, you can alter the height of the rear exhaust tips. Clever and simple.
