I would ask MT if they can get you the short x-pipe if that's all you need. It is the same pipe, just without the extensions coming down from the stock manifolds to the race pipes or cats. I think they can order the shorty if they don't have it in stock. Awhile back I was asking them for the same, and Bob said they could order it in.
EDIT: By extensions, I mean pipe extensions (not o2 extensions).
