[Tigers] Chambered exhaust systems?

[MWood24020 at aol.com]

Back in the day, the DZ302 Camaro Z/28 had a chambered exhaust system as an 
 option...before my time, but I guess it was delivered in the trunk of the 
car  for dealer installation (first "trunk kit"?).
 
Anyhow, it replaced the mufflers, while providing some muffling of noise,  
and resulted in a nice weight loss and better flow.
 
Question: has anyone looked into some type of chambered exhaust system for  
the Tiger? With our space constraints, it seems like it might be an 
interesting  idea. Less weight wouldn't bother me, either ;-)
