its actually really hard to say if modding the whole complete exos setup will make ur INCREASE FC or Decrease FC.

majority of the time, changing to a bigger diameter exos, bigger piping, extractor, usually WILL give u more power, but in return sacrifice FC.

but on the other hand for me, i change my stock 1.3 piping from extractor till muffler.

i got a way bigger FC n increase in power as well.

as long as the extractor has no dents n crack, seems good to go

i would recon K&N over Simota. not to say that simota isnt good. drex they all should carry the them i tink.

but i had the chance to dyno with K&N and Simota b4. on the same day, same tuning. jst swapping the filters. but mine was CONE la.

difference margin between 1-2horsies

another brand which i think its worth getting is AEM.
