X-over Pipe (WTF IS THIS!!!)

Looks like a regular X pipe to me. They're probably trying to do some stupid naming trick: instead of saying "crossover pipe" they use "X" for the cross portion, because X happens to be the type of pipe they are selling.
 
Its the same as mine, I think they just re-badged them the x-over. They are good for the money, I plan on mating my catless X with a Mac catback, and I think it will sound terrorizing, in a good way.
