Instead of guessing, call corsa. When I was building my exhaust, I called magnaflow with a question and they emailed me the blueprints for the muffler. Pretty handy.

Physically I do not know the difference... but once is for each brand.

My guess is that some motors took more intricate noise cancelling chambers inside the muffler to eliminate drone the way corsa wanted to.
