i had to take them off, you guys were right , the lenght of the filters totally destroyed the way the engine ran, although it could have also been a litle bit of it running on 3 cylinders and me not even knowing it(i thought it was supposed to be slow). Im really getting tired of tryin to make this thing ridable and i just bought a complete JDM B16A2 swap for my civic, what do you guys think i could get for the bike RUNNING.
