Yah, my 2016 M235xi ragtop definitely had a better exhaust sound than my 2018 M240xi ragtop.
When in S mode, the M235xi would make a pleasing fart sound on upshifts and pops on downshifts.
I've never heard the farts on upshifts on the M240xi in any mode and only hears minor pops on downshifts if DSC is off.
Other than that, I love my M240xi, it's even more stupid fast than the M235xi.
