So they do exist. Here is the first original impala 4 I have ever seen. It's not mine but a member from a different forum.

Like the impala 2 I thought both of these things didn't actually exist but I have a 2 in the works and here is a 4.

I have come to realise that the actual impala 2 is different to the advertisement. As the only 2 cowlings I've seen are different to the advertisement. The vents on the front of the cowl in the advertisement are different to the actual cowl. It's been a general consensus between me and the owner of the other impala that they may not have the same catcher pictured in the advertisement. But im still going to mock my catcher up to match the original advertisement.

I have circled the difference in the cowling in the last 2 pictures and I've circled it.
