exhaust drone/harmonic resonance

Doubtful you can get enough resonator on the A-body to cut out the resonation the Spin Techs create. They sound cool but like other chambered mufflers, they are not as driver-friendly as they could be.

We are playing with the new DynoMax VTs mufflers and so far, the two cars we have had them on sound good and do not show signs of terrible resonation. Will have more data just as soon as we get new tailpipes from Waldron. These will then be permanently mounted on a 360, 68 Barracuda coupe.
