To each their own. IMO Flowmasters and baffled/chambered mufflers in general seem to direct the sound to a very narrow pitch area, and the pitch doesn't really change with RPM - it simply gets louder. They have a dull, flat, muffled sound.

"Turbo" style mufflers, with internal tubes and packing, like Dynomax Super Turbos, let the pitch change with RPM and IMO maintain more of the traditional crisp "musclecar" sound. Even at the same DB levels IMO turbo mufflers sound crisper than a chambered muffler.

So my opinion is I don't care much for the sound of Flowmasters, especially on stock, low compression motors that don't have a lot of "character" to begin with. Exhausts, like music, takes more than decibels to sound good.

Again, to each their own.
