I just disconnected the airbox intake tubing and replaced it with, nothing. Man what a difference it makes to airflow, the engine seems to breath much easier, though i'm yet to test it extensively. Just the hand infront of inlet whilst throttling before/after. Of course, the resonator is now disconnected too, man, it sure is louder. Much more boomy. But now I'm scared for my warranty guys... :o There's no chance I can damage anything is there?
