Arrow Full System

[Pip1957]

Hi everyone my first post on the board just received my full arrow system after 2 weeks wait from Italy
and to my horror they have sent two right cylinder downpipes and no left one, so will have more delay
before I can fit it. My bike is a 2016 ZE dark grey fitted with power commander FC with o2 optimizers
with 8's in the closed loop area really sorted the surging and abrupt throttle.

8's are the amount of extra fuel added in the closed loop area to help the o2 optimizers maintain 13.6 fuel ratio

hope you don't hate me if I jump in the discussion with a different question, but I figured that it might be better not to open a new discussion since there is a similar one already on.
I am going to purchase the Arrow header system to match it with my Yoshi RSV4 slip on already on my bike since 3 months. Adding also a K&N air filter. Does anybody know if it's really necessary to have my bike retuned of on a dyno after those addictions? I've been riding for more than 20 years but this is the first time I get myself into this kind of modifications and I fear I can put the engine in a not so perfect working condition.

Yes mods and farkles are an addiction aren't they?
