I installed the JCW pro exhaust on my brand new 2021 F56 JCW. Contrary to what is stated on minis website this WILL fit U.S. spec minis no problem, no modification required. It will also fit any mini that doesn't have the gas particle filter (GPF/PPF) in the resonator. If you have a second cat right before your resonator you probably don't have a GPF. If the front of your resonator is rounded and doesn't look exactly like the back of your resonator you probably have a GPF.
Even if you do have a GPF it is possible to have the CEL coded out that will appear due to the removal of the GPF when installing this exhaust.
Alternatively, if you have a GPF, you could cut your stock exhaust behind your resonator and cut a section of the the pro exhaust out and still install the pro exhaust after the stock resonator.
The only issue I ran into is the rubber grommet that comes with the wiring kit doesn't fit in the hole in the floor of the boot on newer minis. mini has changed the design of this grommet/plug. You can find the correct one from ECS tuning for $5-$6. ECS part #: 164380

I have a 2020 Cooper s and I’m pretty sure the JCW pro tuning kit isn’t available for it anymore! I’m in New Zealand though so it may only be here. I may have to get a re map instead!

I think the ECU is not mapped like us in country with the reglementation about the PPF.

@claudetheruler

Do you need to order tuning kit or can you order the pro kit that’s without that second cat???

Good info there brother! I almost gave up until I saw your vid! I am doing my research. I am located in Canada, have a 2021 F56 JCW. Between the pro and Remus I am leaning towards Remus. Contacted Remus Canada and they advised their catback won't fit on facelift due to GPF (they offered an axle-back for S though).. I assume you're in the States, how come yours doesn't have a GPF? I thought they're putting GPF in all NAs? And if I take the Remus route, do you know if cutting a section of the Remus will make everything works? Thanks in advance couldn't found much info for 2021!

Hi Pal. Thank You for proving this works as I couldn’t understand why Mini would stop doing this up grade...

hi, do you have any manual to show how to install this exhaust ?

What’s your mpg in sport mode with those valves open? 🙂 just curious.

I just installed on my 2019 jcw (automatic) the pro exhaust but they left the gpf filter. So again no pops and bangs. Do you believe removing the filter will help having pops and bangs while driving ? I am also afraid that removing the filter will make the car very loud even with the flap closed (having also droning). What is your opinion ?

What production month is your JCW? I have an Oct. 2020 build (2021 MY, for USA) and there is NO over-run burbles whatsoever. I'm at 1350 miles now, and I'm about to give up on this car. I haven't checked for the presence of the GPF yet, but will do so soon. But if there are no burbles now, I don't think just getting the exhaust from ECS is going to change that. Your car seemed to pop and bang like crazy even with the stock exhaust! Just trying to figure out the other side of this mystery, aside from the presence of the GPF. Is it as simple as GPF = no pops and bangs in the ECU tune?

@claudetheruler

This is the tuning kit, not pro kit. Pro kit doesn’t give you pipe with second cat.
