Ever seen muffler right by the rear bumper?

[70stroker]

We have a 75 corvette and the stock muffler location was right at the rear bumber and has about 4 inchs of pipe afterward turned down. It has flowmaster 40s just like my 70. the 70 is currently just dumped before the rear end. I would like to find a way to put these mufflers after the diff and have them turned down. The corvette is alot quiter in the vehicle and sounds awesome when you get on it, its the sound i am after I just dont see a way to mount them back there, and seeing the the truck has not motor currently i cant just run it up to the muffler shop.

Suggestions and pics would be awesome.
