Can you post a few photos of the round one? With dimensions? It should not be too tough to duplicate. I build mufflers for fun. 
I made the Whizzer mufflers that flowed a lot of exhaust and sounded really nice (did this several years ago). These below are for 1970 Vacuum Operated Exhaust equipped GTOs.
