I would definitely reset the mixture after changing from a stock exhaust to a race system and fitting a sprint filter. It will need more fuel.
My 2015 H2 has the Akrapovic race system and a filter change. I bought a Power Commander and had it mapped on a local Dyno'. Back then (2015) not many were reprogramming ECU's so this was the way to go. I'd sent my bike's ECU off to Brock's Performance for a reflash first, worth doing particularly to get a 100% throttle map, the restricted stock map is shown in Ghul Motors' image. This was really easy to do using UPS as a carrier, even though I'm in England and Brock is in the USA. (That's UPS not the USPS) Brock's is a very good company. He will also supply a PCV and probably has a suitable map for you too.
