Rage exhaust location

Hi everyone, I'm just wondering why some rage's exhaust tips are located at the other edges of the transom and some are more to the center, close to the drive? Any advantages either way?

7.4 exhaust header fit 502/450hp

Thanks in advance.
Does a 7.4 mpi stock exhaust +header fit a 502 cid carb long block engine with 450hp?
If it does, does it drop performance?
