I installed new shocks 444 progressives on my 2015 freewheeler, and also have a DK rear lift on it. my problem now is the z tube that connects to the header, and allows a slip muffler to attach to the Z tube. Well the Z tube is now rubbing on the frame. It is about 3/8 to 1/2 inch above the clearance of the cross member (frame). short from taking a hammer to it, I need to know if there is a Harley or after market Z tube? that will clear the cross member frame.
