This bike right now has no PCIII , and the full system running good (with PCIII better performing i know) , while installing this system you have to make some modifications to the bike's main processor . Inside the box of the exhaust there is a quick how to do this modding instruction . This exhaust system has no place to insert O2 sensor so you have to remove some parts from the bike . Without plugging O2 sensor the FI lamb comes on , but as i said up , after that modding , the FI lamb comes off position .
I will install this bike an EM PRO kit , with that kit (EM PRO made of Yoshimura) you can get about 222-223 hp at the krank . This kit does not need a PCIII , it has a self PC inside . That's why i didn't install a PCIII ...
