65 Valiant magnum swap exhuast

My situation I just got some flex pipes off the 273 manifolds to give me a temporary exhaust to get the car on the road and then I will eventually put headers on this thing one way or the other.
Passenger side on trans crossmember obviously is a problem.
Don't know what I'm going to do I might cut a piece of that trans mount or have that two and a half inch pipe bent down to hug around and get around it somehow.
