F56 LCI2 (22+) - JCW Pro or Remus exhaust compatibility

Hello All! I recently picked up a lightly used CPO 2022 F56 JCW (US-Spec). I immediately want to change the stock exhaust to a valved one (Remus or JCW Pro exhaust).
My question is:

1. I have called various Mini Dealers and they all tell me that the JCW Pro Exhaust (Part# 18-30-2-407-323) will not fit the LCI2; i can't return it if I do order it. Has anyone fitted the JCW Pro Exhaust to the LCI2 F56 (JCW) and can confirm the part # to me?
2. As for Remus site for their track OR non-resonated exhaust (Part # 756215 397) it only lists "F56 years 14-18 OR "Not for face lift". In addition for the Facelift version (and even then it only shows 2019-2021) it only shows "Axle-back" options which I don't want. Has anyone fitted the full non-resonated exhaust to an LCI2 and can confirm the part #?
3. For Remus, where are you all ordering the exhaust from? (I've had horrible experiences with Vivid Racing -- damaged Armytrix exhaust system due to poor shipping box protection took months just to get a reply from them)

I just want to make sure either one works before ordering as returning them is either not possible or a hassle due to it's shipping size.

UPDATE (the information below applies to US vehicles):

Luckily (and thankfully) someone locally was selling a used JCW Pro Exhaust off of a 2018 Mini Cooper S and we agreed that if it didn't work on my car they'd take it back and return my money. The following part numbers were stamped on the pipes (both with 2018 build year):

Pipe with Secondary Cat:
18302359649
Pipe with Muffler\Valved: 18302359645

According to the website - the two items will fit 2015-2019 F56 and F57 (all trims). Now obviously you don't want to order the two part numbers above. You'd actually want to order the package (which includes the two parts listed above, plus the wiring, module, Bluetooth, etc)

18302407323 (for JCW trim only as this doesn't include the tune -- it's not needed since you already have a JCW)
11122359631 (for S models as this one includes the JCW Tune)

and I think there may be a revised version of the kit as the rubber grommet changed in the trunk area for certain month in 2019.

With that said, IT FITS ON MY F56 2022 (LCI2) JCW!! Bolts right up!

I have a theory as to why they won't update the supported year list, and that is due to stricter emissions and\or sound level restriction requirements on newer vehicles. As long as they can sell it as up to 2019 cars only, they can sell without issues with the government; but again, that's just my theory.

Thanks for the update, figure that but was not 100% on actual fitment. Yes they can't flash for car at the dealer because the system will not let them do it with the VIN and the fitment based off Vin. MINI people know sometimes their is work arounds.

https://www.ecstuning.com/Search/Sit...h/18302407323/ JCW pre LCI

The one you used its most likely this one for the Cooper S Pre LCI https://www.ecstuning.com/b-genuine-...t/11122359631/

I have a 2024 1to6 on order here in the U.S. Once here, I want to install a JCW Pro-Exhaust. Is it accurate that if I order a JCW Pro Exhaust designed to fit a 2019 JCW, it will bolt right up?

Hello,

It fits the system. See post #3 as its up to the dealers if they want of feel like doing it to make it work. MINI dealers work on a system that tells them per VIN per OEM part number, Not like what we do here on the forums/ECS Tuning that find ways to make things work.

I've got no issue doing the wrenching and installing myself. I just need to confirm with my local dealer that this will not void any warranty.

Yea, local dealers will say anything to get a sale of an oem part. As far as warranty, its always up to them. Its case by case and you can get warranty at one dealer and denied at another. I know I went to 3 different dealers in my area to get warranty done over the years since 2004. Hope they can work with you.

I stopped by my Mini Dealership here in Tempe, AZ and they told me they will order AND install the JCW Pro Exhaust on my 2024 1 to 6 when it arrives! How about THEM APPLES! They charge a pretty penny in labor (six hours) but the warranty will remain in tact without issue! Pretty stoked about that.

and I think there may be a revised version of the kit as the rubber grommet changed in the trunk area for certain month in 2019.

With that said, IT FITS ON MY F56 2022 (LCI2) JCW!! Bolts right up!

I have a theory as to why they won't update the supported year list, and that is due to stricter emissions and\or sound level restriction requirements on newer vehicles. As long as they can sell it as up to 2019 cars only, they can sell without issues with the government; but again, that's just my theory.
Hey QQ, do you happen to know if the "S" model works on the JCW? Bizarre question but the S model is on sale for $1000 and the JCW specific unit is $1600. I'd assume they are the same minus the "tune" which I don't need.

so for us dense owners, let me ask. if i were to buy the jcw pro exhaust and install myself on a GP3 does it have to be programed to the car or can i just wire it to stay open and not wire it the the car?
or does it only have to be coded to the car if it was an S model ?

Were you able to fit the module as well? All the connections ? I understand the exhaust fit but all the Bluetooth stuff to work properly for the valve connected as well?

thanks in advance
