A couple years ago I had a 2016 JCW F56 and looking to get another in 2021, most likely a 2021 model, however I started seeing that the JCW Pro exhaust won't fit 2020+ models, and the engine code is now B46D, not B48. S

Some users report less pops/bangs from the exhaust.

I cannot find any definitive info on the changes. Kinda worried the new ones lost some of their character, or even horse power, or fun to drive behavior. It would be a US car so I don't think the US cars get the particulate exhaust filter.

Does anyone have any more info?

 

I own a brand new 2021 JCW. She has all the pops, burbles, and bangs you could possibly need in sport mode. Mid mode is pretty quiet in stock form. GL!
