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...

There was never a change in 16 besides fixing rattling valves and possibly adjusting some software.
