Needing to replace my exhaust Y pipe. There is a factory crease in the right side pipe. I found a replacement at the bone yard that does not have the same crease just straight tubes to the transom. When removing the existing pipe I did not see any reason for the crease from an external perspective. Anybody know of a reason why the straight tubes would not work.

When looking around on ebay I noticed that some of the later models had the same crease so I am sure there must be some reason. Any takers?
