Okay, I am getting desperate here. What exhaust for the 08-09 Honda DO NOT interfere with the oil filter? And I mean not at all. I don't want to have to undo any part of the exhaust to get the oil filter off. I don't want to have to flex the exhaust to get the oil filter off. I want to be able to take the oil filter off as I would with the stock exhaust. I am talking about full systems for the 08-09 CBR1000RR. All brands. And pics would be GREAT!!!. Thanks.
