RE: muffler design

Check my reply to another topic "Muffler Design Rules"
Thread384-80519 point is that in general,  total system muffler volume will run 5 - 8 engine horspower per liter of muffler displacement,  just as a rule of thumb.  There are of course variations depending on whether the vehicle is a luxury car, a "sporty" car, a truck etc.

The basic design is that the muffler internals consist of a group of both side-branch-type and annular Helmholtz tuners,  designed within the parameters discussed in that other post.
