The exhaust takes a bit to line everything up and adjust, it was my least favorite thing about it. I had to adjust/rotate the mid pipe and the rear section to get it closer. Make sure your hanger rods are pushed through the rubber hangers enough and they should sit almost horizontal.
Tip: That allen bolt looks like its installed upside down; I think the head that's showing should be making contact with the exhaust pipe
take it out by hand and check the other end
