I can't say with the factory stuff, but I had a 72 Satellite/RR with a 440 that had the headers and full exhaust off of a 69 Road Runner installed on it. It seemed to clear everything okay.

The entire drive train and exhaust was swapped into the car.

One thing though, the 71 R/S exhaust flange will be clocked (indexed/ timed/ twisted) different than a 69. That's the difference between a R/S 71 and 69 exhaust manifold (besides the obvious part number difference).

You'd have to use a R/S 69 exhaust manifold without having the exhaust pipe flange reworked/turned.
