Nope, pressed send right before leaving work. Just finished reading it now.

Dynomax mufflers work well. Only thing I don't care for is the insulation inside that can break down over time. In an old car that isn't driven a lot this is a non issue.

Interesting how the Supertrapp does everything just as good, or better in the case of a flow bench reading, than the Dynomax, but ends up being one of the 3 loudest. I would never buy a Supertrapp muffler for an old car, but I do like the fact that they are serviceable and adjustable. They are very popular with dirt bike and ATV racers.

The Borlas flow bench within a hair of the Dynomax, but are a 'slower" muffler down the track.

Muffler companies don't seem to talk about decibel control as that's not as sexy as flow rate, or the type of patented aggressive sound they produce. If they came right out and said our mufflers are super quiet, most would think that would mean a loss in power.
