Oval tubing can help get under the torque arm crossmember also, as long as you have the room to make the transition. Transmission choice will make room for an X-pipe tighter. My engine is moved back 8", but I'm running a 4-speed so the case is considerably shorter than a T56/TR6060. The system wasn't finished when I snapped these pictures but you get the idea. Room for an X if you work at it.
