Any suggestions to solve this?

On the left side, everything looks fine. Perhaps a small Breeze wedge to make muffler parallel to the frame.

However, things are different on the right side. The header needs to come out almost two inches to connect to the muffler. The muffler is also tilted downwards, about an inch and a half. I can most likely make up the space with Breeze spacers but it will not take care of the downward tilting.

Making some measurement, I find the left header is about 2 inches longer than the right cylinder 1 compared to 5. Correct?
