Kawasaki Ninja Zx6r 2024 Tuning. Recently installed a full m4 exhaust system on my 2024 zx6r, what are the next steps i need to take? If speed is what you want go to a zx10r or similar.

What i do is to take the bike when brand new, get it fully warmed up and then go to a quiet backroad and do a series of roll on accelerations in 3rd or 4th gear. Do i need a tune and power commander?
