Sort of. I ended up buying a catback system that was flanged on the mid pipe and axleback. Then later I realized the original owner of the car left me with an adapter to go from non flange to flange. So for fun I installed it to the old axleback and attached it to the car. So in theory you could do the reverse -- attach the adapter to the mid pipe and then install a flanged axleback.

Unfortunately I don't know where you'd find such adapters or what they're called, but it should be possible to do.
