No difference really. But I did not want to touch the OE N54 mid pipe. That sucker sells for something like $2,300!!!! And what would happen IF you ever needed to pass a visual state emission inspection? Thats why I bought the N55 mids.
I think its better to just buy the N55 mid pipe. Its made so well and you will have ZERO fitment or quality issues with it. It was a no brainer for me.
