x-pipe and exit in front of rear tires?

I am also wondering where and how will the mufflers fit underneath the car when it exits at the tire?

As I said, mine was on my old '70 B body. I sold it to some stupid kid in the early '80's. Gauwd do I wish I'd kept that car. As I said, I put the factory RR/ Superbee/ GTX big factory mufflers on it.

Difficult to describe without pics, and WOULD I like to find the guy who bent them, probbly dead by now.

The tailpipes came out of the mufflers, immediately had a gently almost 90 out, then straight back maybe a foot in length under the rockers, then out at about 45 with big "baloney sliced" ends right in front of the outer edge of the tire. Marvelous sound.
