2021 Arrow Headers on a 2019 Z900

[doomguy10011]

I got a nice deal on a very slightly used set of Arrow headers for my Z900. The only thing is, they're from a 2021 model (71727MI) and mine is a 2019 (71661MI). They do fit without any problems, but I just wanted to check if there might be any issues to worry about in the long run. I know that earlier Arrow slip-ons won't fit the newer headers because these have a female outlet rather than a male as in the pre-2020 headers. But that aside, I wanted to see if I could use these headers on my 2019 without running into any performance/heating issues in the long run.

Thanks in advance!

You’re in the U.S. and the exhaust is the same for all years.

Overseas has new standards and a different system after 2021.
