I am trying to understand why my 86 corvette is popping thru the exhaust when I accelerate but still performs well?

If it's "popping" out the exhaust on acceleration, you may think it's running right but it's not performing well.
Without understanding a little more about the problem's characterisics, "popping" or "backfiring" under load when accelerating is often a sign the ignition system needs attention. In what condition are your spark plugs, plug wires and ignition coil?
