Modern Buddy

Was thinking about getting the PERFORMANCE KIT (STAGE 2) from scooterworks. My bike is a 2014 with about 8k miles on it. no real issues as for as performance. do need a new muffler, there is a hole in it. Just wondering if this is a bad upgrade idea for a little bit older bike. I'd like to hear some feedback from you all.

There's no replacement for displacement.

I've not had good luck with upgrades. There's always a trade off, and sometimes I feel foolish for spending xx amount for only .y percentage increase in performance.

Stockers are less likely to give give you reliability issues.
