Nice work!! Love the setup and good to see one routed this way. The way you did it unfortunately won't work for me due to the placement of my oil cooler (it would be in the way of the left lower pipe), but I've been thinking about figuring out if I could go with a high exit, around the same height as the muffler. I think though, due to the width of the muffler and bends coming off it, that the pipes would be on or too near the reverse lights.

Your setup looks great though!
