    I like the gentle growl of a big body magnaflow followed by it screaming at wot.

    Agreed. I didn't run the spin techs long. Sounded good. But to loud for me

    flowmasters are loud, drone, and don't flow that well. a quality straight through muffler like a dynomax ultraflow or magnaflow will run circles around a flowmaster, and the wrapped perforated tube design really resists droning like a chambered muffler does. my single 3" magnaflow is very mild under normal driving loads and screams at WOT, and has such a smooth refined tone.

    There was a joke about my truck having "world ending" exhaust when I had my Spintech. It does sound amazing. It's sounds completely different from anything else. Flowmaster 10s sound like garbage compared to a Spintech.
