Seen a couple threads on the ZCP exhaust vs non-ZCP and the difference is noticeable. ZCP is louder but in the comparisons its always been compared to a 2015 exhaust/m3/m4...
There's comparisons of 2015 vs non-ZCP 2016 exhausts and 2016 is louder.
Question is, is it possible the ZCP exhaust note is the same as a 2016
or are there now 3 different exhaust notes..2015, 2016 & 2016 ZCP...
