I started Boxstiring 8 years ago. I have a vague recolletion of the Korda muffler and almost no recollection of Sportech.

I do remember there was one company that cut open a muffler, and welded it back up. Might have been Fabspeed.

If it was cut open I called it a Frankenstein muffler.

At our work on cars days I heard a Frankenstein muffler, and it had a rattle inside.

I do not usually trust dyno graphs.

I took this picture of the spec class at Laguna Seca. They are required to run with the stock manifolds, but after that it is free.

Some of the cars had dual aftermarket mufflers. The tips were crimped to increase back pressure, or to increase torque.

Funny how that works in reality.
