It is perfectly possible, however not very sensible as then you would not be able to drive car without hearing protection and it adds next to nothing in performance wise.

The best thing to do is probably to replace it with a straight through backbox. That will give you the skinny inlet and fat tailpipe you're looking for, with a louder sound to boot...

Measure diameter of pipe end (joint before back box), go to parts shop and ask sport exhaust that would mate up with that diameter pipe, I believe that is easiest and best working method.
