OK, cool.
Here is the car sent to me by Dicanio.
I looked it up on ServiceBox, and here are the basic specs.
It seems to me to be a pretty normal series 1 GTi, the gold colour is factory, the wheel arch "flares" are standard for GTi and GTi180, and CC, not SP flares or anything else.
The remus exhaust looks to have the surround cut out of the bumper to make it fit, which is different to how the twin tips on the 180, or the single devil exhaust was done.
The engine is listed as the standard EW10J4.
Based on what you've said above, the Cat Cams, BMC airbox, remus exhaust and RC 200 badge are probably aftermarket additions in the nearly 18 years since it was built. You didn't send a photo of the badge, so it's hard to verify if it looks factory or not.
Unless it's had a major swap done, it's not an EW12, although it would probably fit with a fair bit of fiddling. EW12 has VVT and CANbus, which the early 206's don't have (aka pre-mux), so it could be a complex ECU job to make it work.
I don't know what more you're trying to find out, we're only curious about a car you have presented as being a total orphan. It doesn't look to be that way, in fact it looks like a standard GTi that someone has modified to their liking.
Best of luck with it, nice looking car.
