I changed the tubes to opposite sides and then they fit properly, it does seem like a little bit could be trimmed from the tubes however. (I did not trim anything).

So in conclusion they do fit without being trimmed and unfortunately I couldn't detect any difference from stock other than a small mpg boost. However, I am sure they are giving some power increase, even if the butt dyno can't tell, and I do not regret the purchase at all.
