I am travelling to Cali (south + north) for 6 months later this year to visit my in-laws and wanted to do a few track days.
Wanted to know if the older (short pipe) full Akro exhaust will be too loud (for some tracks)? Or should I bring a quieter bike (and/or put on the stock exhaust back?)
There are a few tracks that limit decibel levels (e.g., Laguna Seca), but you should be fine so long as you get off the throttle a bit when you’re passing the sound marshal stations.
Both have limits, however, you should be fine at T-Hill and Sonoma. Laguna's limits are typically pretty low (some stock bikes/pipes are too loud), unless you happen catch one of the few higher limit days.
