x-pipe and exit in front of rear tires?

no, this is for my 68 cuda, with that 318 i rebuilt and had break in problems with, but all is better, and a rebuilt front end. if this works out okay, i'll probably do the same thing on my 70 dart with the 408. im anxious to know what these mufflers sound like. probably this weekend ill clamp them on and test fire it up.
