Can i leave it off?

Good evening, i picked up a monty muffler today to replace the old one and i find this big lump of thing behind the bumperbar, it doesnt seem to have any use that i can see other than give the bumperbar (fibreglass) some support if someone rear ends me??, it has alfoil wrapped over it , i suppose intended to keep heat from turbo away??

It weighs about 30kg also

Any thoughts
Can i leave it off?

The first pic looks like it is the bumperbar. That 30kg bar is what saves you if you get rearended. There are shocks to take some of the punch too. These are mounted behind the bumperettes i think which also help out
The one in fiberglass is just the bumper "cover" for looks and aesthetics and will not stop anything.
DO NOT LEAVE THIS OFF!

The other picture i`m not sure and maby someone else can chime in

If I am not entirely mistaken, that second one is the heat shield, fending off turbo and exhaust heat from the fan area..

If all that gets too hot, all the fan is sucking in is hot air.

What year is that? Is it a grey market car from the '80's?

This is correct - - Heat shield.

I would keep them both. Just my opinion for safety.

You state 930, your car is either a 964 or a 930 with a 964 conversion.. from the pics it appears to have a 964 conversion.

The first lump is the bumper impact bar and the 2nd pic is the heat-shield. You have either plastic or fiberglass bumpers. The heat from the turbo will cook the paint and possibly melt the bumpber without the shield. The impact bar is self explanatory.
