Tom Tweed might want venture here and post the sport muffler modification pic (or do a search for ttweed - sport muffler). Basically it's open up the right end of the muffler, then cut an opening in an internal bulkhead; cut a flap at the top and create similar openings in two other bulkheads.

You can use a cutoff tool to create the flap, but for all other operations you'll need the services of a welder and some pipe material - curved for a right side tailpipe and straight, twin pipes for a factory sport muffler look.
