JCW Pro Exhaust for GP3

Hello, I am looking at purchasing a JCW Pro exhaust from ESC tuning. I can see they have 3 different ones. The one that has caught my eye due to the massive price difference is 1122359631. believe this version is for Cooper S 2014-2019. There is 18302407323 which is for JCW only 2015-2019 but some reason is $700 more than the cooper s version despite cooper s version needing the tuning file (doesnt make sense to me). There is a third version, 18302475191 for 2020-2021 Cooper S and JCW which would probably be the one I would need.

My question is, can I purchase the cheaper cooper s version for the exhaust only and wire it up to the vehicle (not activate the tuning file obviously) and will it work for my 2020 GP3? $700 price difference is wild and eye watering

MINI priced the older ones (they have tons in stock) to sell, they used to be much higher.

The JCW did not get a tune so its just a switch.

I was trying to find someone that install one on a GP3 but i did not find it. We had some people wire them in on 2022+ JCWs.

All these kits are close in design, they were given different part numbers based on what the dealer installs, box unit, and flashes per VIN. Remember when dealer installs its up to them to match the VIN on genuine and these kits so everyone knows.

Its pick one and try it as the GP3 is its own weird beast. I know the closest would be the JCW F56 of the 2021 should be the one to get?
